Detailed Description

Interface for message encoding method for public key signature schemes.

PK_SignatureMessageEncodingMethod provides interfaces for message encoding method for public key signature schemes. The methods support both trapdoor functions (TF_*) and discrete logarithm (DL_*) based schemes.
