CKM_SHA3_256_HMAC_GENERAL
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.
