Use the PKCS #11 Pseudo-random callable service to generate pseudo-random output of arbitrary length. This service does not support any recovery methods.

The mechanism keyword specified in the rule array indicates what derivation protocol to use. The derive parms list provides additional input/output data. The format of this list is dependent on the protocol being used.

The callable service can be invoked in AMODE(24), AMODE(31), or AMODE(64). 64-bit callers must use CSFPPRF6.
