+<h3><a name="dev"></a>
+ <a href="http://lxr.mozilla.org/mozilla/source/security/nss/lib/dev/"> 
+ Device</a>
+ </h3>
+                          Defines cryptoki devices used in NSS. &nbsp;This
+ is  not   part  of the exposed API. &nbsp;It is a low-level API allowing
+NSS to manage   cryptoki  devices.<br>
+ <br>
+         The relationship is like this:<br>
+ <br>
+         libpki --&gt; libdev --&gt; cryptoki<br>
+ <br>
+         As an example,<br>
+ <br>
+         NSSTrustDomain_FindCertificate --&gt; NSSToken_FindCertificate --&gt;
+   C_FindObjects<br>
+ <br>
+ <a href="http://lxr.mozilla.org/mozilla/ident?i=NSSModule">NSSModule</a>
+ <br>
+                     Replaces the SECMOD API. &nbsp;The module manages a
+PRLibrary       that   holds  a cryptoki implementation via a number of slots.
+&nbsp;The      API should   provide  the ability  to Load and Unload a module,
+Login  and    Logout to the   module (through its slots), and to locate a
+particular   slot/token.<br>
+ <br>
+ <a href="http://lxr.mozilla.org/mozilla/ident?i=NSSSlot">NSSSlot</a>
+ <br>
+                     This and NSSToken combine to replace the PK11 API parts
+  that   relate    to  slot  and token management. &nbsp;The slot API should
+  provide   the ability   to Login/Logout   to a slot, check the login status,
+  determine    basic configuration    information   about the slot, and modify
+  the password    settings.<br>
+ 
+<ol>
+   <li>Should slots also maintain a default session? &nbsp;This session would 
+ be used for slot management calls (sections 9.5 and9.6 of PKCS#11). &nbsp;Or 
+ is the token session sufficient (this would not work if C_GetTokenInfo and 
+ C_InitToken need to be wrapped in a threadsafe session).<br>
+   </li>
+ 
+</ol>
+ <br>
+ <a href="http://lxr.mozilla.org/mozilla/ident?i=NSSToken">NSSToken</a>
+ <br>
+                     Fills in the gaps left by NSSSlot. &nbsp;Much of the 
+cryptoki     API   is  directed   towards slots.  &nbsp;However,   some  functionality
+   clearly belongs with a token type. &nbsp;For  example,   a certificate
+ lives  on a token, not a slot, so one would expect  a function   NSSToken_FindCertificate.
+    &nbsp;Thus functions that deal with  importing/exporting   an object
+and    performing  actual cryptographic operations  belong here.<br>
+ 
+<ol>
+   <li>The   distinction  between a slot and a token is not clear. &nbsp;Most 
+   functions take  a slotID   as an argument,  even though it is obvious that
+     the event   is intended to occur on a token. &nbsp;That leaves various
+   possibilities:</li>
+   
+  <ol>
+     <li>Implement the API entirely as NSSToken. &nbsp;If the token  is not 
+  present, some calls will simply fail.</li>
+     <li>Divide the API between NSSToken and NSSSlot, as described  above. 
+&nbsp;NSSSlot  would handle cryptoki calls specified as "slot management",
+  while NSSToken  handles actual token operations.</li>
+     <li>Others?</li>
+   
+  </ol>
+   <li>Session management. &nbsp;Tokens needs a threadsafe session handle 
+ to perform operations. &nbsp;CryptoContexts are meant to provide such sessions, 
+ but other objects will need access to token functions as well (examples: 
+the TrustDomain_Find functions, _Login, _Logout, and others that do not exist 
+ such as NSSToken_ChangePassword). &nbsp;For those functions, the token could 
+ maintain a default session. &nbsp;Thus all NSSToken API functions would take
+ sessionOpt as an argument. &nbsp;If the caller is going to provide a session,
+ it sends an NSSSession there, otherwise it sends NULL and the default session
+ is utilized.<br>
+   </li>
+ 
+</ol>
+      Proposed:<br>
+    NSSSession<br>
+    Wraps a Cryptoki session. &nbsp;Created from a slot. &nbsp;Used to manage
+  sessions for crypto contexts. &nbsp;Has a lock field, which locks the session
+  if the slot is not threadsafe.<br>

+ 
+<ol>
+   <li>The API leaves open the possibility of NSSCertificate meaning  various 
+ certificate types, not just X.509. &nbsp;The way to keep open this  possibility 
+ is to keep only generally useful information in the NSSCertificate  type. 
+&nbsp;Examples would be the certificate encoding, label, trust (obtained
+ from cryptoki calls), an email address, etc. &nbsp;Some type of generic
+reference  should be kept to the decoded certificate, which would then be
+accessed by  a type-specific API (e.g., NSSX509_GetSubjectName).</li>

+ <br>
+                    A trust domain is "the field in which certificates may
+ be  validated."       &nbsp;It  is a collection of modules capable of performing 
+  cryptographic      operations  and storing certs and keys. &nbsp;This collection 
+  is managed     by NSS in a manner opaque to the consumer. &nbsp;The slots 
+  will have various      orderings determining which has preference for a 
+given  operation. &nbsp;For      example, the trust domain may order the storage
+ of user certificates one    way, and the storage of email certificates in
+ another way [is that a good    example?].<br>
+ <br>
+ 
+<ol>
+   <li>           How will ordering work? &nbsp;We already have the  suggestion 
+      that  there be two kinds of ordering: storage and search.  &nbsp;How 
+will     they be  constructed/managed? &nbsp;Do we want to expose  access 
+to a token     that overrides  this ordering (i.e., the download of  updated 
+root certs   may  need to override  storage order)</li>
+   <li>How are certs cached? &nbsp;Nelson wonders what it means   to   Stan 
+    when a cert does not live on a token yet. &nbsp;Bob, Terry, and    I discussed
+    this. &nbsp;My conclusion is that there should be a type,  separate 
+from   NSSCertificate,  that holds the decoded cert parts (e.g.,   NSSX509Certificate,
+    or to avoid confusion, NSSX509DecodedParts). &nbsp;NSSCertificate   would
+  keep  a handle to this type, so that it only needs to decode the  cert
+once.   &nbsp;The  NSSTrustDomain would keep a hash table of cached certs, 
+some of  which may  not live on a token yet (i.e., they are only NSSX509DecodedParts). 
+     &nbsp;This  cache could be accessed in the same way the temp db was, 
+and    when the cert  is ready to be moved onto a token a call to NSSTrustDomain_ImportCertificate 
+       is made. &nbsp;Note    that this is essentially the same as CERT_TempCertToPerm.</li>
+   
+  <ul>
+     <li>The hashtable in lib/base (copied from ckfw/hash.c) uses the identity 
+hash. &nbsp;Therefore, in a hash of certificates, the key is the certificate 
+pointer itself. &nbsp;One possibility is to store the decoded cert (NSSX509DecodedParts 
+above) as the value in the {key, value} pair. &nbsp;When a cert is decoded, 
+the cert pointer and decoding pointer are added to the hash. &nbsp;Subsequent 
+lookups have access to one or both of these pointers. &nbsp;This keeps NSSCertificate 
+separate from its decoding, while providing a way to locate it.</li>
+   
+  </ul>
+   <li>The API is designed to keep token details hidden from the user.  &nbsp;However, 
+ it has already been realized that PSM and CMS may need special  access to 
+tokens. &nbsp;Is this part of the TrustDomain API, or should PSM  and CMS 
+be allowed to use "friend" headers from the Token API?</li>
+   <li>Do we want to allow traversal via NSSTrustDomain_TraverseXXXX?<br>
+   </li>

+       Testing Stan</h3>
+       A&nbsp;new command line tool, pkiutil, has been created to use only
+ the   Stan API. &nbsp;It depends on a new library, cmdlib, meant to replace
+ the   old secutil library. &nbsp;The old library had code used by products
+ that   needed to be integrated into the main library codebase somehow. &nbsp;The
+   goal of the new cmdlib is to have functionality needed strictly for NSS
+ tools.<br>
+ <br>
+       How to build:<br>
+ 
+<ol>
+   <li>cd nss/cmd/cmdlib; make</li>
+   <li>cd ../pkiutil; make</li>
+ 
+</ol>
+       pkiutil will give detailed help with either "pkiutil -?" or "pkiutil 
+ --help".<br>
+ <br>
+      So far, the only available test is to list certs on the builtins token. 
+  &nbsp;Copy "libnssckbi.so" (or whatever it is) to cmd/pkiutil. &nbsp;Then 
+  run "pkiutil -L" or "pkiutil --list". &nbsp;The list of certificate nicknames 
+  should be displayed.<br>
