SA22-7522-16

Use the PKCS #11 Generate HMAC callable service to generate a hashed message authentication code (MAC). This service does not support any recovery methods.

The key handle must be a handle of a PKCS #11 generic secret key object. The mechanism keyword specified in the rule array indicates the hash algorithm to use. The CKA_SIGN attribute for the secret key object must be true.

The callable service can be invoked in AMODE(24), AMODE(31), or AMODE(64). 64-bit callers must use CSFPHMG6.
