Class GOST3410Signer

public class GOST3410Signer extends Object implements DSA

GOST R 34.10-94 Signature Algorithm
Method Summary
BigInteger[]generateSignature(byte[] message)
generate a signature for the given message using the key we were initialised with.
voidinit(boolean forSigning, CipherParameters param)
booleanverifySignature(byte[] message, BigInteger r, BigInteger s)
return true if the value r and s represent a GOST3410 signature for the passed in message for standard GOST3410 the message should be a GOST3411 hash of the real message to be verified.

Method Detail

generateSignature

public BigInteger[] generateSignature(byte[] message)
generate a signature for the given message using the key we were initialised with. For conventional GOST3410 the message should be a GOST3411 hash of the message of interest.

Parameters: message the message that will be verified later.

init

public void init(boolean forSigning, CipherParameters param)

verifySignature

public boolean verifySignature(byte[] message, BigInteger r, BigInteger s)
return true if the value r and s represent a GOST3410 signature for the passed in message for standard GOST3410 the message should be a GOST3411 hash of the real message to be verified.
