+ * FUNCTION: PKIX_Initialize
+ * DESCRIPTION:
+ *
+ * No PKIX_* types and functions should be used before this function is called
+ * and returns successfully. This function should only be called once. If it
+ * is called more than once, the behavior is undefined.
+ *
+ * NSS applications are expected to call NSS_Init, and need not know that
+ * NSS will call this function (with "platformInitNeeded" set to PKIX_FALSE).
+ * PKIX applications are expected instead to call this function with
+ * "platformInitNeeded" set to PKIX_TRUE.
+ *
+ * This function initializes data structures critical to the operation of
+ * libpkix. It also ensures that the API version (major.minor) desired by the
+ * caller (the "desiredMajorVersion", "minDesiredMinorVersion", and
+ * "maxDesiredMinorVersion") is compatible with the API version supported by
+ * the library. As such, the library must support the "desiredMajorVersion"
+ * of the API and must support a minor version that falls between
+ * "minDesiredMinorVersion" and "maxDesiredMinorVersion", inclusive. If
+ * compatibility exists, the function returns NULL and stores the library's
+ * actual minor version at "pActualMinorVersion" (which may be greater than
+ * "desiredMinorVersion"). If no compatibility exists, the function returns a
+ * PKIX_Error pointer. If the caller wishes to specify that the largest
+ * minor version available should be used, then maxDesiredMinorVersion should
+ * be set to the macro PKIX_MAX_MINOR_VERSION (defined in pkixt.h).

+ *      has previously been run, or should be called from this function.

+ *  If called with a NULL "state", this function attempts to build and validate
+ *  a CertChain according to the ProcessingParams pointed to by "params", using
+ *  an RFC 3280-compliant validation algorithm. If successful, this function
+ *  returns NULL and stores the BuildResult at "pResult", which holds the built
+ *  CertChain, as well as additional information, such as the policy tree and
+ *  the target's public key. If unsuccessful, an Error is returned.
+ *
+ *  If the chain building is blocked by a CertStore using non-blocking I/O, this
+ *  function stores platform-dependent non-blocking I/O context at
+ *  "pNBIOContext", its state at "pState", and NULL at "pResult". The caller
+ *  may be able to determine, in a platform-dependent way, when the I/O has
+ *  completed. In any case, calling the function again with "pState" containing
+ *  the returned value will allow the chain building to resume.
+ *
+ *  If chain building is completed, either successfully or unsuccessfully, NULL
+ *  is stored at "pNBIOContext".
+ *
+ *  If "pVerifyTree" is non-NULL, a tree of VerifyNodes is created which
+ *  tracks the results of the building. That is, each node of the tree either
+ *  has a NULL Error component, or it is a leaf node and it contains an Error
+ *  which indicates why the chain building could not proceed on this branch.
+ *
+ * PARAMETERS:
+ *  "params"

+ *      Must be non-NULL.
+ *  "pNBIOContext"
+ *      Address where platform-dependent information is store if the build

+ * used to retrieve certificates from a CertStore that match the selector's
+ * criteria. (See pkix_certstore.h) For example, the caller may wish to only
+ * select those certificates that have a particular Subject Distinguished Name
+ * and a particular value for a private certificate extension. The
+ * MatchCallback allows the caller to specify the custom matching logic to be
+ * used by a CertSelector.
+ *
+ * By default, the MatchCallback is set to point to the default implementation
+ * provided by libpkix, which understands how to process the most common
+ * parameters. If the default implementation is used, the caller should set
+ * these common parameters using PKIX_CertSelector_SetCommonCertSelectorParams.
+ * Any common parameter that is not set is assumed to be disabled, which means
+ * the default MatchCallback implementation will select all certificates
+ * without regard to that particular disabled parameter. For example, if the
+ * SerialNumber parameter is not set, MatchCallback will not filter out any
+ * certificate based on its serial number. As such, if no parameters are set,
+ * all are disabled and any certificate will match. If a parameter is
+ * disabled, its associated PKIX_ComCertSelParams_Get* function returns a
+ * default value of NULL, or -1 for PKIX_ComCertSelParams_GetBasicConstraints
+ * and PKIX_ComCertSelParams_GetVersion, or 0 for
+ * PKIX_ComCertSelParams_GetKeyUsage.
+ *
+ * If a custom implementation is desired, the default implementation can be
+ * overridden by calling PKIX_CertSelector_SetMatchCallback. In this case, the
+ * CertSelector can be initialized with a certSelectorContext, which is where
+ * the caller can specify the desired parameters the caller wishes to match
+ * against. Note that this certSelectorContext must be an Object (although any
+ * object type), allowing it to be reference-counted and allowing it to
+ * provide the standard Object functions (Equals, Hashcode, ToString, Compare,
+ * Duplicate).

+/* PKIX_CertStore
+ *
+ * A PKIX_CertStore provides a standard way for the caller to retrieve
+ * certificates and CRLs from a particular repository (or "store") of
+ * certificates and CRLs, including LDAP directories, flat files, local
+ * databases, etc. The CertCallback allows custom certificate retrieval logic
+ * to be used while the CRLCallback allows custom CRL retrieval logic to be
+ * used. Additionally, a CertStore can be initialized with a certStoreContext,
+ * which is where the caller can specify configuration data such as the host
+ * name of an LDAP server. Note that this certStoreContext must be an
+ * Object (although any object type), allowing it to be reference-counted and
+ * allowing it to provide the standard Object functions (Equals, Hashcode,
+ * ToString, Compare, Duplicate). Please note that each certStoreContext must
+ * provide Equals and Hashcode functions in order for the caching (on Cert and
+ * CertChain) to work correctly. When providing those two functions, it is not
+ * required that all the components of the object be hashed or checked for 
+ * equality, but merely that the functions distinguish between unique
+ * instances of the certStoreContext.
+ *
+ * Once the caller has created the CertStore object, the caller then specifies
+ * these CertStore objects in a ProcessingParams object and passes that object
+ * to PKIX_ValidateChain or PKIX_BuildChain, which uses the objects to call the
+ * user's callback functions as needed during the validation or building
+ * process.
+ *
+ * The order of CertStores stored (as a list) at ProcessingParams determines
+ * the order in which certificates are retrieved. Trusted CertStores should
+ * precede non-trusted ones on the list of CertStores so their certificates
+ * are evaluated ahead of other certificates selected on the basis of the same
+ * selector criteria.
+ *
+ * The CheckTrustCallback function is used when the CertStore object
+ * supports trust status, which means a Cert's trust status can be altered
+ * dynamically. When a CertStore object is created, if the
+ * CheckTrustCallback is initialized to be non-NULL, this CertStore is

+ * FUNCTION: PKIX_CertStore_CertCallback
+ * DESCRIPTION:

+ *  This callback function retrieves from the CertStore pointed to by "store"

+ *  It places these certificates in a List and stores a pointer to the List at
+ *  "pCerts". If no certificates are found which match the CertSelector's

+ *
+ *  A CertStore which uses non-blocking I/O may store platform-dependent
+ *  information at "pNBIOContext" and NULL at "pCerts" to indicate that I/O is
+ *  pending. A subsequent call to PKIX_CertStore_CertContinue is required to
+ *  finish the operation and to obtain the List of Certs.
+ *
+ *  Note that the List returned by this function is immutable.

+/* PKIX_CertChainChecker
+ *
+ * PKIX_CertChainCheckers provide a standard way for the caller to insert their
+ * own custom checks to validate certificates. This may be useful in many
+ * scenarios, including when the caller wishes to validate private certificate
+ * extensions. The CheckCallback allows custom certificate processing to take
+ * place. Additionally, a CertChainChecker can optionally maintain state
+ * between successive calls to the CheckCallback. This certChainCheckerState
+ * must be an Object (although any object type), allowing it to be
+ * reference-counted and allowing it to provide the standard Object functions
+ * (Equals, Hashcode, ToString, Compare, Duplicate). If the caller wishes
+ * their CertChainChecker to be used during chain building, their
+ * certChainCheckerState object must implement an appropriate Duplicate
+ * function. The builder uses this Duplicate function when backtracking.
+ *
+ * Once the caller has created a CertChainChecker object, the caller then
+ * specifies a CertChainChecker object in a ProcessingParams object
+ * and passes the ProcessingParams object to PKIX_ValidateChain or
+ * PKIX_BuildChain, which uses the objects to call the user's callback
+ * functions as needed during the validation or building process.
+ *
+ * A CertChainChecker may be presented certificates in the "reverse" direction
+ * (from trust anchor to target) or in the "forward" direction (from target to
+ * trust anchor). All CertChainCheckers must support "reverse checking", while
+ * support for "forward checking" is optional, but recommended. If "forward
+ * checking" is not supported, building chains may be much less efficient. The
+ * PKIX_CertChainChecker_IsForwardCheckingSupported function is used to
+ * determine whether forward checking is supported, and the
+ * PKIX_CertChainChecker_IsForwardDirectionExpected function is used to
+ * determine whether the CertChainChecker has been initialized to expect the
+ * certificates to be presented in the "forward" direction.

+ * FUNCTION: PKIX_CertChainChecker_CheckCallback
+ * DESCRIPTION:
+ *
+ *  This callback function checks whether the specified Cert pointed to by
+ *  "cert" is valid using "checker's" internal certChainCheckerState (if any)
+ *  and removes the critical extensions that it processes (if any) from the
+ *  List of OIDs (possibly empty) pointed to by "unresolvedCriticalExtensions".
+ *  If the checker finds that the certificate is not valid, an Error pointer is
+ *  returned.
+ *
+ *  If the checker uses non-blocking I/O, the address of a platform-dependent
+ *  non-blocking I/O context ("nbioContext") will be stored at "pNBIOContext",
+ *  which the caller may use, in a platform-dependent way, to wait, poll, or
+ *  otherwise determine when to try again. If the checker does not use
+ *  non-blocking I/O, NULL will always be stored at "pNBIOContext". If a non-NULL
+ *  value was stored, on a subsequent call the checker will attempt to complete
+ *  the pending I/O and, if successful, NULL will be stored at "pNBIOContext".
+ *
+ * PARAMETERS:
+ *  "checker"
+ *      Address of CertChainChecker whose certChainCheckerState and
+ *      CheckCallback logic is to be used. Must be non-NULL.

+ *  A CertChainChecker may be presented certificates in the "reverse"

+ *  presented. This is particularly useful for CertChainCheckers that are
+ *  capable of checking in either the "forward" direction or the "reverse"
+ *  direction, but have different processing steps depending on the direction.
+ *
+ *  The CertChainChecker also uses the List of OIDs pointed to by "extensions"
+ *  as the supported certificate extensions. All certificate extensions that
+ *  the CertChainChecker might possibly recognize and be able to process
+ *  should be included in the List of supported extensions. If "checker" does

+ * A function returns NULL upon success, and a PKIX_Error pointer upon failure.
+ *
+ * Unless otherwise noted, for all accessor (gettor) functions that return a

+ * shared object. Therefore, the caller should treat this shared object as
+ * read-only and should not modify this shared object. When done using the
+ * shared object, the caller should release the reference to the object by
+ * using the PKIX_PL_Object_DecRef function.
+ *
+ * While a function is executing, if its arguments (or anything referred to by

+ * PKIX_ProcessingParams are parameters used when validating or building a
+ * chain of certificates. Using the parameters, the caller can specify several
+ * things, including the various inputs to the PKIX chain validation
+ * algorithm (such as trust anchors, initial policies, etc), any customized
+ * functionality (such as CertChainCheckers, RevocationCheckers, CertStores),
+ * and whether revocation checking should be disabled.
+ *
+ * Once the caller has created the ProcessingParams object, the caller then
+ * passes it to PKIX_ValidateChain or PKIX_BuildChain, which uses it to call
+ * the user's callback functions as needed during the validation or building
+ * process.
+ *
+ * If a parameter is not set (or is set to NULL), it will be set to the
+ * default value for that parameter. The default value for the Date parameter
+ * is NULL, which indicates the current time when the path is validated. The
+ * default for the remaining parameters is the least constrained.

+ * shared object. Therefore, the caller should treat this shared object as
+ * read-only and should not modify this shared object. When done using the
+ * shared object, the caller should release the reference to the object by
+ * using the PKIX_PL_Object_DecRef function.

+/* PKIX_Logger
+ *
+ * PKIX_Loggers provide a standard way for the caller to insert custom logging

+ * Additionally, a Logger can be initialized with a loggerContext, which is
+ * where the caller can specify configuration data such as the name of a
+ * logfile or database. Note that this loggerContext must be a PKIX_PL_Object,
+ * allowing it to be reference-counted and allowing it to provide the standard
+ * PKIX_PL_Object functions (Equals, Hashcode, ToString, Compare, Duplicate).
+ *
+ * Once the caller has created the Logger object(s) (and set the loggerContext
+ * (if any) and the Log callback), the caller then registers these Loggers
+ * with the system by calling PKIX_SetLoggers or PKIX_AddLogger. All log
+ * entries will then be logged using the specified Loggers. If multiple
+ * Loggers are specified, every log entry will be logged with each of them.

+/* Error
+ *
+ * An Error object is returned by a function upon encountering some error
+ * condition. Each Error is associated with an errorCode specified in pkixt.h.
+ * The remaining components of an Error are optional. An Error's description
+ * specifies a text message describing the Error. An Error's supplementary info
+ * specifies additional information that might be useful. Finally, an Error's
+ * cause specifies the underlying Error (if any) that resulted in this Error
+ * being returned, thereby allowing Errors to be chained so that an entire
+ * "error stack trace" can be represented. Once created, an Error is immutable.
+ *
+ * Note that the Error's supplementary info must be an Object (although any
+ * object type), allowing it to be reference-counted and allowing it to
+ * provide the standard Object functions (Equals, Hashcode, ToString, Compare,
+ * Duplicate).
+ *
+ * Errors are classified as either being fatal or non-fatal. If a function
+ * fails in an unrecoverable way, it returns an Error whose errorCode is
+ * PKIX_FATAL_ERROR. If such an error is encountered, the caller should
+ * not attempt to recover since something seriously wrong has happened

+ * Because C does not typically have automatic garbage collection, the caller
+ * is expected to release the reference to any object that they create or that
+ * is returned to them by a libpkix function. The caller should do this by
+ * using the PKIX_PL_Object_DecRef function. Note that the caller should not

+ *
+ *  In order to match against this criterion, there are several possibilities.

+ *  1) If the criterion's minimum path length is greater than or equal to zero,

+ *
+ *  2) If the criterion's minimum path length is -2, a certificate must be an
+ *  end-entity certificate.
+ *
+ *  3) If the criterion's minimum path length is -1, no basic constraints check
+ *  is done and all certificates are considered to match this criterion.
+ *
+ * PARAMETERS:
+ *  "params"
+ *      Address of ComCertSelParams whose basic constraints field is used.
+ *      Must be non-NULL.

+ *  disabled and any certificate will match. If a parameter is disabled, its
+ *  associated PKIX_ComCertSelParams_Get* function returns a default value.
+ *  That value is -1 for PKIX_ComCertSelParams_GetBasicConstraints and

+ * FUNCTION: pkix_PolicyChecker_CalculateIntersection
+ * DESCRIPTION:
+ *
+ *  Processes the PolicyNode pointed to by "currentNode", and its descendants,
+ *  using the PolicyCheckerState pointed to by "state", using the List at
+ *  the address pointed to by "nominees" the OIDs of policies that are in the
+ *  user-initial-policy-set but are not represented among the nodes at the
+ *  bottom of the tree, and storing at "pShouldBePruned" the value TRUE if
+ *  currentNode is childless at the end of this processing, FALSE if it has
+ *  children or is at the bottom of the tree.
+ *
+ *  When this function is called at the top level, "nominees" should be the List
+ *  of all policies in the user-initial-policy-set. Policies that are
+ *  represented in the valid-policy-node-set are removed from this List. As a
+ *  result when nodes are created according to 6.1.5.(g)(iii)(3)(b), a node will
+ *  be created for each policy remaining in this List.
+ *
+ *  This function implements the calculation of the intersection of the
+ *  validPolicyTree with the user-initial-policy-set, as described in
+ *  RFC 3280 6.1.5(g)(iii).
+ *
+ * PARAMETERS:
+ *  "currentNode"
+ *      Address of PolicyNode whose descendants will be processed as described.
+ *      Must be non-NULL.
+ *  "state"
+ *      Address of the current state of the PKIX_PolicyChecker. Must be non-NULL
+ *  "nominees"
+ *      Address of List of the OIDs for which nodes should be created to replace
+ *      anyPolicy nodes. Must be non-NULL but may be empty.
+ *  "pShouldBePruned"
+ *      Address where Boolean return value, set to TRUE if this PolicyNode
+ *      should be deleted, is stored. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Not Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds
+ *  Returns a CertChainChecker Error if the functions fails in a non-fatal way
+ *  Returns a Fatal Error if the function fails in an unrecoverable way

+ *  Performs the wrap-up processing for the Cert pointed to by "cert",
+ *  using and updating the PolicyCheckerState pointed to by "state".
+ *
+ *  This function implements the wrap-up processing described in RFC3280
+ *  Section 6.1.5, after the final certificate has been processed. Section
+ *  references in the comments are to that document.
+ *
+ * PARAMETERS:
+ *  "cert"
+ *      Address of the current (presumably the end entity) certificate.
+ *      Must be non-NULL.
+ *  "state"
+ *      Address of the current state of the PKIX_PolicyChecker.
+ *      Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Not Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds
+ *  Returns a CertChainChecker Error if the functions fails in a non-fatal way
+ *  Returns a Fatal Error if the function fails in an unrecoverable way

+ *  Boolean value of "initialAnyPolicyInhibit" for the inhibitAnyPolicy
+ *  parameter, and the UInt32 value of "numCerts" as the number of
+ *  certificates in the chain; and stores the Checker at "pChecker".
+ *
+ * PARAMETERS:
+ *  "initialPolicies"
+ *      Address of List of OIDs comprising the user-initial-policy-set; the List
+ *      may be empty or NULL
+ *  "policyQualifiersRejected"
+ *      Boolean value of the policyQualifiersRejected parameter
+ *  "initialPolicyMappingInhibit"
+ *      Boolean value of the inhibitPolicyMappings parameter
+ *  "initialExplicitPolicy"
+ *      Boolean value of the initialExplicitPolicy parameter
+ *  "initialAnyPolicyInhibit"
+ *      Boolean value of the inhibitAnyPolicy parameter
+ *  "numCerts"
+ *      Number of certificates in the chain to be validated
+ *  "pChecker"
+ *      Address to store the created PolicyChecker. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds
+ *  Returns a CertChainChecker Error if the functions fails in a non-fatal way
+ *  Returns a Fatal Error if the function fails in an unrecoverable way

+ *
+ *  Creates a new CertChainChecker and stores it at "pChecker", where it will
+ *  used by pkix_TargetCertChecker_Check to check that the final certificate
+ *  of a chain meets the criteria of the CertSelector pointed to by
+ *  "certSelector". The number of certs remaining in the chain, represented by
+ *  "certsRemaining" is used to initialize the checker's state.
+ *
+ * PARAMETERS:
+ *  "certSelector"
+ *      Address of CertSelector representing the criteria against which the
+ *      final certificate in a chain is to be matched. May be NULL.
+ *  "certsRemaining"
+ *      Number of certificates remaining in the chain.
+ *  "pChecker"
+ *      Address where object pointer will be stored. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a CertChainChecker Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ * DESCRIPTION:
+ *  This function compares the parameter values (Issuer, date, and CRL number)
+ *  set in the ComCRLSelParams of the CRLSelector pointed to by "selector" with
+ *  the corresponding values in the CRL pointed to by "crl". When all the
+ *  criteria set in the parameter values match the values in "crl", PKIX_TRUE is
+ *  stored at "pMatch". If the CRL does not match the CRLSelector's criteria,
+ *  PKIX_FALSE is stored at "pMatch".
+ *
+ * PARAMETERS
+ *  "selector"
+ *      Address of CRLSelector which is verified for a match
+ *      Must be non-NULL.
+ *  "crl"
+ *      Address of the CRL object to be verified. Must be non-NULL.
+ *  "pMatch"
+ *      Address at which Boolean result is stored. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ *
+ * THREAD SAFETY:
+ *  Conditionally Thread Safe
+ *      (see Thread Safety Definitions in Programmer's Guide)
+ *
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a CRLSelector Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ * FUNCTION: pkix_Build_VerifyCertificate
+ * DESCRIPTION:
+ *
+ *  Checks whether the previous Cert stored in the ForwardBuilderState pointed
+ *  to by "state" successfully chains, including signature verification, to the
+ *  candidate Cert also stored in "state", using the Boolean value in "trusted"
+ *  to determine whether "candidateCert" is trusted.
+ *
+ *  First it checks whether "candidateCert" has already been traversed by
+ *  determining whether it is contained in the List of traversed Certs. It then
+ *  checks the candidate Cert with user checkers, if any, in the List pointed to
+ *  by "userCheckers". Finally, it runs the signature validation.
+ *
+ *  If this Certificate fails verification, and state->verifyNode is non-NULL,
+ *  this function sets the Error code into the verifyNode.
+ *
+ * PARAMETERS:
+ *  "state"
+ *      Address of ForwardBuilderState to be used. Must be non-NULL.
+ *  "userCheckers"
+ *      Address of a List of CertChainCheckers to be used, if present, to
+ *      validate the candidateCert.
+ *  "trusted"
+ *      Boolean value of trust for the candidate Cert
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a Build Error if the function fails in a non-fatal way
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ *  Checks whether the current List of Certs successfully validates using the

+ *  the Cert List, in "state".
+ *
+ *  If a checker using non-blocking I/O returns with a non-NULL non-blocking I/O
+ *  context (NBIOContext), an indication that I/O is in progress and the
+ *  checking has not been completed, this function stores that context at
+ *  "pNBIOContext". Otherwise, it stores NULL at "pNBIOContext".
+ *
+ *  If not awaiting I/O and if successful, a ValidateResult is created
+ *  containing the Public Key of the target certificate (including DSA parameter
+ *  inheritance, if any) and the PolicyNode representing the policy tree output
+ *  by the validation algorithm.  If not successful, an Error pointer is
+ *  returned.
+ *
+ * PARAMETERS:
+ *  "state"
+ *      Address of ForwardBuilderState to be used. Must be non-NULL.
+ *  "anchor"
+ *      Address of TrustAnchor to be used. Must be non-NULL.
+ *  "pNBIOContext"
+ *      Address at which the NBIOContext is stored indicating whether the

+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a Build Error if the function fails in a non-fatal way

+ * FUNCTION: pkix_Build_GatherCerts
+ * DESCRIPTION:
+ *
+ *  This function traverses the CertStores in the List of CertStores contained
+ *  in "state",  using the certSelector and other parameters contained in
+ *  "state", to obtain a List of all available Certs that satisfy the criteria.
+ *  If a CertStore has a cache, "certSelParams" is used both to query the cache
+ *  and, if an actual CertStore search occurred, to update the cache. (Behavior
+ *  is undefined if "certSelParams" is different from the parameters that were
+ *  used to initialize the certSelector in "state".)
+ * 
+ *  If a CertStore using non-blocking I/O returns with an indication that I/O is
+ *  in progress and the checking has not been completed, this function stores
+ *  platform-dependent information at "pNBIOContext". Otherwise it stores NULL
+ *  at "pNBIOContext", and state is updated with the results of the search.
+ *
+ * PARAMETERS:
+ *  "state"
+ *      Address of ForwardBuilderState to be used. Must be non-NULL.
+ *  "certSelParams"
+ *      Address of ComCertSelParams which were used in creating the current
+ *      CertSelector, and to be used in querying and updating any caches that
+ *      may be associated with with the CertStores.
+ *  "pNBIOContext"
+ *      Address at which platform-dependent information is returned if request
+ *      is suspended for non-blocking I/O. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a Build Error if the function fails in a non-fatal way
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ * FUNCTION: pkix_BuildForwardDepthFirstSearch
+ * DESCRIPTION:
+ *
+ *  This function performs a depth first search in the "forward" direction (from
+ *  the target Cert to the trust anchor). A non-NULL targetCert must be stored
+ *  in the ForwardBuilderState before this function is called. It is not written
+ *  recursively since execution may be suspended in in any of several places
+ *  pending completion of non-blocking I/O. This iterative structure makes it
+ *  much easier to resume where it left off.
+ *
+ *  Since the nature of the search is recursive, the recursion is handled by
+ *  chaining states. That is, each new step involves creating a new
+ *  ForwardBuilderState linked to its predecessor. If a step turns out to be
+ *  fruitless, the state of the predecessor is restored and the next alternative
+ *  is tried. When a search is successful, values needed from the last state
+ *  (canBeCached and validityDate) are copied to the state provided by the
+ *  caller, so that the caller can retrieve those values.
+ *
+ *  There are three return arguments, the NBIOContext, the ValidateResult and
+ *  the ForwardBuilderState. If NBIOContext is non-NULL, it means the search is
+ *  suspended until the results of a non-blocking IO become available. The
+ *  caller may wait for the completion using platform-dependent methods and then
+ *  call this function again, allowing it to resume the search. If NBIOContext
+ *  is NULL and the ValidateResult is non-NULL, it means the search has
+ *  concluded successfully. If the NBIOContext is NULL but the ValidateResult is
+ *  NULL, it means the search was unsuccessful.
+ *
+ *  This function performs several steps at each node in the constructed chain:
+ *
+ *  1) It retrieves Certs from the registered CertStores that match the
+ *  criteria established by the ForwardBuilderState pointed to by "state", such
+ *  as a subject name matching the issuer name of the previous Cert. If there
+ *  are no matching Certs, the function returns to the previous, or "parent",
+ *  state and tries to continue the chain building with another of the Certs
+ *  obtained from the CertStores as possible issuers for that parent Cert.
+ *
+ *  2) For each candidate Cert returned by the CertStores, this function checks
+ *  whether the Cert is valid. If it is trusted, this function checks whether
+ *  this Cert might serve as a TrustAnchor for a complete chain.
+ *
+ *  3) It determines whether this Cert, in conjunction with any of the
+ *  TrustAnchors, might complete a chain. A complete chain, from this or the
+ *  preceding step, is checked to see whether it is valid as a complete
+ *  chain, including the checks that cannot be done in the forward direction.
+ *
+ *  4) If this Cert chains successfully, but is not a complete chain, that is,
+ *  we have not reached a trusted Cert, a new ForwardBuilderState is created
+ *  with this Cert as the immediate predecessor, and we continue in step (1),
+ *  attempting to get Certs from the CertStores with this Certs "issuer" as
+ *  their subject.
+ *
+ *  5) If an entire chain validates successfully, then we are done. A
+ *  ValidateResult is created containing the Public Key of the target
+ *  certificate (including DSA parameter inheritance, if any) and the
+ *  PolicyNode representing the policy tree output by the validation algorithm,
+ *  and stored at pValResult, and the function exits returning NULL.
+ *
+ *  5) If the entire chain does not validate successfully, the algorithm
+ *  discards the latest Cert and continues in step 2 with the next candidate
+ *  Cert, backing up to a parent state when no more possibilities exist at a
+ *  given level, and returning failure when we try to back up but discover we
+ *  are at the top level.
+ *
+ * PARAMETERS:
+ *  "pNBIOContext"
+ *      Address at which platform-dependent information is returned if building
+ *      is suspended for non-blocking I/O. Must be non-NULL.
+ *  "pState"
+ *      Address at which input ForwardBuilderState is found, and at which output
+ *      ForwardBuilderState is stored. Must be non-NULL.
+ *  "pValResult"
+ *      Address at which the ValidateResult is stored. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a Build Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ * 
+ * PARAMETERS:
+ *  "state"
+ *      Address of ForwardBuilderState to be used. Must be non-NULL.
+ *  "pBuildResult"
+ *      Address at which the BuildResult is stored, after a successful build.
+ *      Must be non-NULL.
+ *  "pNBIOContext"
+ *      Address at which the NBIOContext is stored indicating whether the
+ *      validation is complete. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a Build Error if the function fails in a non-fatal way
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ * FUNCTION: pkix_Build_InitiateBuildChain
+ * DESCRIPTION:
+ *
+ *  This function initiates the search for a BuildChain, using the parameters
+ *  provided in "procParams" and, if continuing a search that was suspended
+ *  for I/O, using the ForwardBuilderState pointed to by "pState".
+ *
+ *  If a successful chain is built, this function stores the BuildResult at
+ *  "pBuildResult". Alternatively, if an operation using non-blocking I/O
+ *  is in progress and the operation has not been completed, this function
+ *  stores the platform-dependent non-blocking I/O context (nbioContext) at
+ *  "pNBIOContext", the FowardBuilderState at "pState", and NULL at
+ *  "pBuildResult". Finally, if chain building was unsuccessful, this function
+ *  stores NULL at both "pState" and at "pBuildResult".
+ *
+ *  Note: This function is re-entered only for the case of non-blocking I/O
+ *  in the "short-cut" attempt to build a chain using the target Certificate
+ *  directly with one of the trustAnchors. For all other cases, resumption
+ *  after non-blocking I/O is via pkix_Build_ResumeBuildChain.
+ *
+ * PARAMETERS:
+ *  "procParams"

+ * FUNCTION: pkix_Build_ResumeBuildChain
+ * DESCRIPTION:
+ *
+ *  This function continues the search for a BuildChain, using the parameters
+ *  provided in "procParams" and the ForwardBuilderState pointed to by "state".
+ *
+ *  If a successful chain is built, this function stores the BuildResult at
+ *  "pBuildResult". Alternatively, if an operation using non-blocking I/O
+ *  is in progress and the operation has not been completed, this function
+ *  stores the FowardBuilderState at "pState" and NULL at "pBuildResult".
+ *  Finally, if chain building was unsuccessful, this function stores NULL
+ *  at both "pState" and at "pBuildResult".
+ *
+ * PARAMETERS:
+ *  "pNBIOContext"
+ *      Address at which the NBIOContext is stored indicating whether the
+ *      validation is complete. Must be non-NULL.
+ *  "pState"
+ *     Address at which the ForwardBuilderState is provided for resumption of
+ *     the chain building attempt; also, the address at which the
+ *     ForwardBuilderStateis stored, if the chain building is suspended for
+ *     waiting I/O. Must be non-NULL.
+ *  "pBuildResult"
+ *      Address at which the BuildResult is stored, after a successful build.
+ *      Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a Build Error if the function fails in a non-fatal way
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ *
+ *  This function should be called initially with the UInt32 pointed to by
+ *  "pCheckerIndex" containing zero, and the pointer at "pNBIOContext"
+ *  containing NULL. If a checker does non-blocking I/O, this function will
+ *  return with the index of that checker stored at "pCheckerIndex" and a
+ *  platform-dependent non-blocking I/O context stored at "pNBIOContext".
+ *  A subsequent call to this function with those values intact will allow the
+ *  checking to resume where it left off. This should be repeated until the
+ *  function returns with NULL stored at "pNBIOContext".
+ *
+ * PARAMETERS:
+ *  "cert"
+ *      Address of Cert to validate. Must be non-NULL.
+ *  "checkers"
+ *      List of CertChainCheckers which must each validate the certificate.
+ *      Must be non-NULL.
+ *  "checkedExtOIDs"
+ *      List of PKIX_PL_OID that has been processed. If called from building
+ *      chain, it is the list of critical extension OIDs that has been
+ *      processed prior to validation. May be NULL.
+ *  "pCheckerIndex"
+ *      Address at which is stored the the index, within the List "checkers",
+ *      of a checker whose processing was interrupted by non-blocking I/O.
+ *      Must be non-NULL.
+ *  "pNBIOContext"
+ *      Address at which is stored platform-specific non-blocking I/O context.

+ * FUNCTION: pkix_CheckChain
+ * DESCRIPTION:
+ *
+ *  Checks whether the List of Certs pointed to by "certs", containing
+ *  "numCerts" entries, successfully validates using each CertChainChecker in
+ *  the List pointed to by "checkers" and has not been revoked, according to any
+ *  of the Revocation Checkers in the List pointed to by "revChecker". Checkers
+ *  are expected to remove from "removeCheckedExtOIDs" and extensions that they
+ *  process. Indices to the certChain and the checkerChain are obtained and
+ *  returned in "pCertCheckedIndex" and "pCheckerIndex", respectively. These
+ *  should be set to zero prior to the initial call, but may be changed (and
+ *  must be supplied on subsequent calls) if processing is suspended for non-
+ *  blocking I/O. Each time a Cert passes from being validated by one of the
+ *  CertChainCheckers to being checked by a Revocation Checker, the Boolean
+ *  stored at "pRevChecking" is changed from FALSE to TRUE. If the Cert is
+ *  rejected by a Revocation Checker, its reason code is returned at
+ *  "pReasonCode. If the List of Certs successfully validates, the public key i
+ *  the final certificate is obtained and stored at "pFinalSubjPubKey" and the
+ *  validPolicyTree, which could be NULL, is stored at pPolicyTree. If the List
+ *  of Certs fails to validate, an Error pointer is returned.
+ *
+ *  If "pVerifyTree" is non-NULL, a chain of VerifyNodes is created which
+ *  tracks the results of the validation. That is, either each node in the
+ *  chain has a NULL Error component, or the last node contains an Error
+ *  which indicates why the validation failed.
+ *
+ *  The number of Certs in the List, represented by "numCerts", is used to
+ *  determine which Cert is the final Cert.
+ *
+ * PARAMETERS:
+ *  "certs"
+ *      Address of List of Certs to validate. Must be non-NULL.
+ *  "numCerts"
+ *      Number of certificates in the List of certificates.
+ *  "checkers"
+ *      List of CertChainCheckers which must each validate the List of
+ *      certificates. Must be non-NULL.
+ *  "revChecker"
+ *      List of RevocationCheckers which must each not reject the List of
+ *      certificates. May be empty, but must be non-NULL.
+ *  "removeCheckedExtOIDs"
+ *      List of PKIX_PL_OID that has been processed. If called from building
+ *      chain, it is the list of critical extension OIDs that has been
+ *      processed prior to validation. Extension OIDs that may be processed by
+ *      user defined checker processes are also in the list. May be NULL.
+ *  "procParams"
+ *      Address of ProcessingParams used to initialize various checkers. Must
+ *      be non-NULL.
+ *  "pCertCheckedIndex"
+ *      Address where Int32 index to the Cert chain is obtained and
+ *      returned. Must be non-NULL.
+ *  "pCheckerIndex"
+ *      Address where Int32 index to the CheckerChain is obtained and
+ *      returned. Must be non-NULL.
+ *  "pRevChecking"
+ *      Address where Boolean is obtained and returned, indicating, if FALSE,
+ *      that CertChainCheckers are being called; or, if TRUE, that RevChecker
+ *      are being called. Must be non-NULL.
+ *  "pReasonCode"
+ *      Address where UInt32 results of revocation checking are stored. Must be
+ *      non-NULL.
+ *  "pNBIOContext"
+ *      Address where platform-dependent context is stored if checking is
+ *      suspended for non-blocking I/O. Must be non-NULL.
+ *  "pFinalSubjPubKey"
+ *      Address where the final public key will be stored. Must be non-NULL.
+ *  "pPolicyTree"
+ *      Address where the final validPolicyTree is stored. Must be non-NULL.
+ *  "pVerifyTree"
+ *      Address where a VerifyTree is stored, if non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a Validate Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ *  PKIX_Logger. If satisfies, it invokes the callback in PKIX_Logger and
+ *  passes a PKIX_PL_String that is the concatenation of "message" and 
+ *  "message2" to the application for processing. 
+ *  Since this call is inserted into a handful of PKIX macros, no macros are
+ *  applied in this function, to avoid infinite recursion.
+ *  If an error occurs, this call is aborted.
+ *
+ * PARAMETERS:
+ *  "pkixLoggersList"
+ *      A list of PKIX_Loggers to be examined for invoking callback. Must be
+ *      non-NULL.
+ *  "message"
+ *      Address of "message" to be logged. Must be non-NULL.
+ *  "message2"
+ *      Address of "message2" to be concatenated and logged. May be NULL.
+ *  "logComponent"
+ *      A PKIX_UInt32 that indicates the component the message is from.
+ *  "maxLevel"
+ *      A PKIX_UInt32 that represents the level of severity of the message.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds
+ *  Returns a Fatal Error if the function fails in an unrecoverable way

+ * FUNCTION: pkix_CacheCert_Lookup
+ * DESCRIPTION:
+ *
+ *  Look up Cert Hash Table for a cached item based on "store" and Subject in
+ *  "certSelParams" as the hash keys and returns values Certs in "pCerts".
+ *  If there isn't an item to match the key, a PKIX_FALSE is returned at
+ *  "pFound". The item's cache time is verified with "testDate". If out-dated,
+ *  this item is removed and PKIX_FALSE is returned at "pFound".
+ *  This hashtable is maintained in the following ways:
+ *  1) When creating the hashtable, maximum bucket size can be specified (0 for
+ *     unlimited). If items in a bucket reaches its full size, an new addition
+ *     will trigger the removal of the old as FIFO sequence.
+ *  2) A PKIX_PL_Date created with current time offset by constant 
+ *     CACHE_ITEM_PERIOD_SECONDS is attached to each item in the Hash Table.
+ *     If the CertStore this Cert is from is a trusted one, the cache period is
+ *     shorter so cache can be updated more frequently.
+ *     When an item is retrieved, this date is compared against "testDate" for
+ *     validity. If comparison indicates this item is expired, the item is
+ *     removed from the bucket.
+ *
+ * PARAMETERS:
+ *  "store"
+ *      Address of CertStore as key to retrieve this CertChain. Must be 
+ *      non-NULL.
+ *  "certSelParams"
+ *      Address of ComCertSelParams that its subject is used as key to retrieve
+ *      this CertChain. Must be non-NULL.
+ *  "testDate"
+ *      Address of PKIX_PL_Date for verifying time cache validity.
+ *      Must be non-NULL. If testDate is NULL, this cache item won't be out
+ *      dated.
+ *  "pFound"
+ *      Address of KPKIX_Boolean indicating valid data is found.
+ *      Must be non-NULL.
+ *  "pCerts"
+ *      Address PKIX_List where the CertChain will be stored. Must be no-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns an Error Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ *      The AIAMgr whose LDAPClient connected are to be managed. Must be
+ *      non-NULL.
+ *  "domainName"
+ *      Address of a string pointing to a server name. Must be non-NULL.
+ *      An empty string (which means no <host> is given in the LDAP URL) is
+ *      not supported.
+ *  "pClient"
+ *      Address at which the returned LDAPClient is stored. Must be non-NULL.
+ *  "plContext"

+ *  Returns NULL if the function succeeds.

+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:

+ * FUNCTION: pkix_pl_Pk11CertStore_CertQuery
+ * DESCRIPTION:
+ *
+ *  This function obtains from the database the Certs specified by the
+ *  ComCertSelParams pointed to by "params" and stores the resulting
+ *  List at "pSelected". If no matching Certs are found, a NULL pointer
+ *  will be stored.
+ *
+ *  This function uses a "smart" database query if the Subject has been set
+ *  in ComCertSelParams. Otherwise, it uses a very inefficient call to
+ *  retrieve all Certs in the database (and run them through the selector).
+ *
+ * PARAMETERS:
+ * "params"
+ *      Address of the ComCertSelParams. Must be non-NULL.
+ * "pSelected"
+ *      Address at which List will be stored. Must be non-NULL.
+ * "plContext"
+ *      Platform-specific context pointer
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a CertStore Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ *
+ * PARAMETERS
+ *  "isCA"
+ *      Boolean value with the desired value of CA Flag.
+ *  "pathLen"
+ *      a PKIX_Int32 with the desired value of path length
+ *  "pObject"
+ *      Address of object pointer's destination. Must be non-NULL.
+ *  "plContext" - Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a CertBasicConstraints Error if the function fails

+ *  but a NULL List is preferable so a user does not need to call

+ *
+ * PARAMETERS
+ *  "oid"
+ *      OID of the desired PolicyInfo ID; must be non-NULL
+ *  "qualifiers"
+ *      List of CertPolicyQualifiers; may be NULL or empty
+ *  "pObject"
+ *      Address where object pointer will be stored. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.

+ * FUNCTION: pkix_pl_OcspResponse_Create
+ * DESCRIPTION:
+ *
+ *  This function transmits the OcspRequest pointed to by "request" and obtains
+ *  an OcspResponse, which it stores at "pOcspResponse". If the HTTPClient
+ *  supports non-blocking I/O this function may store a non-NULL value at
+ *  "pNBIOContext" (the WOULDBLOCK condition). In that case the caller should
+ *  make a subsequent call with the same value in "pNBIOContext" and
+ *  "pOcspResponse" to resume the operation. Additional WOULDBLOCK returns may
+ *  occur; the caller should persist until a return occurs with NULL stored at
+ *  "pNBIOContext".
+ *
+ *  If a SEC_HttpClientFcn "responder" is supplied, it is used as the client
+ *  to which the OCSP query is sent. If none is supplied, the default responder
+ *  is used.
+ *
+ *  If an OcspResponse_VerifyCallback "verifyFcn" is supplied, it is used to
+ *  verify the Cert received from the responder as the signer. If none is
+ *  supplied, the default verification function is used.
+ *
+ *  The contents of "request" are ignored on calls subsequent to a WOULDBLOCK
+ *  return, and the caller is permitted to supply NULL.
+ *
+ * PARAMETERS
+ *  "request"
+ *      Address of the OcspRequest for which a response is desired.
+ *  "httpMethod"
+ *      GET or POST
+ *  "responder"
+ *      Address, if non-NULL, of the SEC_HttpClientFcn to be sent the OCSP
+ *      query.
+ *  "verifyFcn"
+ *      Address, if non-NULL, of the OcspResponse_VerifyCallback function to be
+ *      used to verify the Cert of the OCSP responder.

+ * FUNCTION: pkix_UTF16_to_EscASCII
+ * DESCRIPTION:
+ *
+ *  Converts array of bytes pointed to by "utf16String" with length of
+ *  "utf16Length" (which must be even) into a freshly allocated Escaped ASCII
+ *  string and stores a pointer to that string at "pDest" and stores the
+ *  string's length at "pLength". The Escaped ASCII string's length does not
+ *  include the final NUL character. The caller is responsible for freeing
+ *  "pDest" using PKIX_PL_Free. If "debug" is set, uses EscASCII_Debug
+ *  encoding.
+ *
+ * PARAMETERS:
+ *  "utf16String"
+ *      Address of array of bytes representing data source. Must be non-NULL.
+ *  "utf16Length"
+ *      Length of data source. Must be even.
+ *  "debug"
+ *      Boolean value indicating whether debug mode is desired.
+ *  "pDest"
+ *      Address where data will be stored. Must be non-NULL.
+ *  "pLength"
+ *      Address where data length will be stored. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:
+ *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns a String Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.
