General-length RIPE-MD 160-HMAC

The general-length RIPE-MD 160-HMAC mechanism, denoted CKM_RIPEMD160_HMAC_GENERAL, is a mechanism for signatures and verification. It uses the HMAC construction, based on the RIPE-MD 160 hash function. The keys it uses are generic secret keys.

It has a parameter, a CK_MAC_GENERAL_PARAMS, which holds the length in bytes of the desired output. This length should be in the range 0-20 (the output size of RIPE-MD 160 is 20 bytes). Signatures (MACs) produced by this mechanism will be taken from the start of the full 20-byte HMAC output.
