public class ECGOST3410Signer
extends java.lang.Object
GOST R 34.10-2001 Signature Algorithm
BigInteger[] | generateSignature(byte[] message) - generate a signature for the given message using the key we were
initialised with.
|
void | init(boolean forSigning, CipherParameters param)
|
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).

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.

- the message that will be verified later.
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).
