+ * a specific certificate or key depends.

+ * A client program, or a simple server, would typically have one
+ * trust domain.  A server supporting multiple "virtual servers" might
+ * have a separate trust domain for each virtual server.  The separate
+ * trust domains might share some modules (e.g., a hardware crypto
+ * accelerator) but not others (e.g., the tokens storing the different

+ * root certificates).

+ * TLS socket connection, etc.  Each crypto context is "in" a
+ * specific trust domain, and it may have associated with it a
+ * distinguished certificate, public key, private key, and/or
+ * symmetric key.  It can also temporarily hold and use temporary
+ * data (e.g. intermediate certificates) which is not stored
+ * permanently in the trust domain.
+ *
+ * In OO terms, this interface inherits interfaces from the trust
+ * domain, the certificates, and the keys.  It also provides
