Encoding Method for Signatures, Appendix
abstract void update(const(ubyte)* input, size_t length);
- Parameters
const(ubyte)* input some data size_t length length of input in bytes
Add more data to the signature computation
abstract SecureVector!ubyte rawData();
- Returns
- raw hash
abstract SecureVector!ubyte encodingOf(ref const SecureVector!ubyte msg, size_t output_bits, RandomNumberGenerator rng);
final SecureVector!ubyte encodingOf(const SecureVector!ubyte msg, size_t output_bits, RandomNumberGenerator rng);
- Parameters
SecureVector!ubyte msg the result of rawData() size_t output_bits the desired output bit size RandomNumberGenerator rng a random number generator - Returns
- encoded signature
Return the encoding of a message
abstract bool verify(ref const SecureVector!ubyte coded, ref const SecureVector!ubyte raw, size_t key_bits);
- Parameters
SecureVector!ubyte coded the received (coded) message representative SecureVector!ubyte raw the computed (local, uncoded) message representative size_t key_bits the size of the key in bits - Returns
- true if coded is a valid encoding of raw, otherwise false
Verify the encoding
