unsigned int | SignAndRestart (RandomNumberGenerator &rng, PK_MessageAccumulator &messageAccumulator, byte *signature, bool restart) const |
sign and restart messageAccumulator | |
unsigned int | SignatureLength () const |
signature length if it only depends on the key, otherwise 0 | |
unsigned int | MaxRecoverableLength () const |
length of longest message that can be recovered, or 0 if this signature scheme does not support message recovery | |
unsigned int | MaxRecoverableLengthFromSignatureLength (unsigned int signatureLength) const |
length of longest message that can be recovered from a signature of given length, or 0 if this signature scheme does not support message recovery | |
bool | IsProbabilistic () const |
requires a random number generator to sign | |
bool | AllowNonrecoverablePart () const |
whether or not a non-recoverable message part can be signed | |
bool | RecoverablePartFirst () const |
whether you must input the recoverable part before the non-recoverable part during signing | |

create a new HashTransformation to accumulate the message to be signed | |
