public interface MessageSigner

Base interface for a PQC signing algorithm.

Method Summary

byte[]	generateSignature(byte[] message) sign the passed in message (usually the output of a hash function).
void	init(boolean forSigning, CipherParameters param) initialise the signer for signature generation or signature verification.
boolean	verifySignature(byte[] message, byte[] signature) verify the message message against the signature value.

Method Detail

init

public void init(boolean forSigning,
                 CipherParameters param)

initialise the signer for signature generation or signature verification.

Parameters:

forSigning - true if we are generating a signature, false otherwise.

param - key parameters for signature generation.

generateSignature

public byte[] generateSignature(byte[] message)

sign the passed in message (usually the output of a hash function).

Parameters:

message - the message to be signed.

Returns:

the signature of the message

verifySignature

public boolean verifySignature(byte[] message,
                               byte[] signature)

verify the message message against the signature value.

Parameters:

message - the message that was supposed to have been signed.

signature - the signature of the message
