This + is not part of the exposed API.

The module manages a +PRLibrary that holds a cryptoki implementation via a number of slots. + 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. 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? This session would + be used for slot management calls (sections 9.5 and9.6 of PKCS#11). 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. Much of the +cryptoki API is directed towards slots. However, some functionality + clearly belongs with a token type. For example, a certificate + lives on a token, not a slot, so one would expect a function NSSToken_FindCertificate. + 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. Most + functions take a slotID as an argument, even though it is obvious that + the event is intended to occur on a token. That leaves various + possibilities:</li> + + <ol> + <li>Implement the API entirely as NSSToken. If the token is not + present, some calls will simply fail.</li> + <li>Divide the API between NSSToken and NSSSlot, as described above. + NSSSlot would handle cryptoki calls specified as "slot management", + while NSSToken handles actual token operations.</li> + <li>Others?</li> + + </ol> + <li>Session management. Tokens needs a threadsafe session handle + to perform operations. 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). For those functions, the token could + maintain a default session. Thus all NSSToken API functions would take + sessionOpt as an argument.

The way to keep open this possibility + is to keep only generally useful information in the NSSCertificate type. + Examples would be the certificate encoding, label, trust (obtained + from cryptoki calls), an email address, etc. 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> + +</ol> + <br> + <a href="http://lxr.mozilla.org/mozilla/ident?i=NSSUserCertificate">NSSUserCertificate</a> + <br> + +<ol> + <li>Should this be a typedef of NSSCertificate?

It is a collection of modules capable of performing + cryptographic operations and storing certs and keys. This collection + is managed by NSS in a manner opaque to the consumer. The slots + will have various orderings determining which has preference for a +given operation. 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? We already have the suggestion + that there be two kinds of ordering: storage and search. How +will they be constructed/managed? 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? Nelson wonders what it means to Stan + when a cert does not live on a token yet. Bob, Terry, and I discussed + this. 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). NSSCertificate would + keep a handle to this type, so that it only needs to decode the cert +once. 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). + 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. 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. Therefore, in a hash of certificates, the key is the certificate +pointer itself. One possibility is to store the decoded cert (NSSX509DecodedParts +above) as the value in the {key, value} pair. When a cert is decoded, +the cert pointer and decoding pointer are added to the hash. Subsequent +lookups have access to one or both of these pointers. 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. However, + it has already been realized that PSM and CMS may need special access to +tokens. 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> + +</ol> + <a href="http://lxr.mozilla.org/mozilla/ident?i=NSSCryptoContext"><br> + NSSCryptoContext</a> + <br> + Analgous to a Cryptoki session.
