Cryptographic Token Interface Standard

PKCS#11


Scope

A number of cryptographic mechanisms (algorithms) are supported in this version. In addition, new mechanisms can be added later without changing the general interface. It is possible that additional mechanisms will be published from time to time in separate documents; it is also possible for token vendors to define their own mechanisms (although, for the sake of interoperability, registration through the PKCS process is preferable).
