Detailed Description

template<bool ALLOW_RECOVERY, class MGF = P1363_MGF1, int SALT_LEN = -1, int MIN_PAD_LEN = 0, bool USE_HASH_ID = false>
class PSSR_MEM< ALLOW_RECOVERY, MGF, SALT_LEN, MIN_PAD_LEN, USE_HASH_ID >

PSSR Message Encoding Method.

Template Parameters

ALLOW_RECOVERY	flag indicating whether the scheme provides message recovery
MGF	mask generation function
SALT_LEN	length of the salt
MIN_PAD_LEN	minimum length of the pad
USE_HASH_ID	flag indicating whether the HashId is used

If ALLOW_RECOVERY is true, the the signature scheme provides message recovery. If ALLOW_RECOVERY is false, the the signature scheme is appendix, and the message must be provided during verification.
