BigInteger[] | 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, BigInteger r, BigInteger s)
verify the message message against the signature values r and s.

Parameters: message the message to be signed.
Returns: two big integers representing the r and s values respectively.
Parameters: forSigning true if we are generating a signature, false otherwise. param key parameters for signature generation.
Parameters: message the message that was supposed to have been signed. r the r signature value. s the s signature value.
