| public BigInteger[] generateSignature(byte[] message) Implements org. 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.

| getOrder | back to summary |
|---|---|
| public BigInteger getOrder() Implements org. Doc from org. Get the order of the group that the r, s values in signatures belong to. | |
| init | back to summary |
|---|---|
| public void init(boolean forSigning, CipherParameters param) Implements org. Doc from org. initialise the signer for signature generation or signature verification.
| |
| verifySignature | back to summary |
|---|---|
| public boolean verifySignature(byte[] message, BigInteger r, BigInteger s) Implements org. 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).
