CKM_SM3_HMAC_GENERAL
SM3 is a hash function published by the Chinese Commercial Cryptography Administration Office for the use of electronic authentication service system. The design of SM3 builds upon the design of the SHA-2 hash function, but introduces additional strengthening features. For Luna PCIe HSM 7s, the available mechanisms are CKM_SM3, the hash function, and CKM_SM3_KEY_DERIVATION, and CKM_SM3_HMAC.
TIP Some mechanisms in this collection have both a "general" variant and a similarly named variant without "general" in the name. Per the PKCS#11 specification the _GENERAL variant of mechanism accepts a mechanism parameter that is used to define the length of the signature that is returned. The length can typically be any value between 1 and the length of the underlying HASH algorithm.
The variants without _GENERAL do not accept any mechanism parameters and always return a fixed length signature; where the length is defined by the underlying HASH algorithm.
