Full Domain HashFrom CryptoDox, The Online Encyclopedia on Cryptography and Information SecurityFull Domain Hash (FDH) is an RSAbased signature scheme that follows the hashanddecrypt paradigm. FDH involves hashing a message using a function whose image size equals the size of the RSA modulus, and then raising it to the secret RSA exponent. Thus hashing and padding are combined into a single step. It is roughly the digital signature analogue of RSAOAEP. External Links
