  • Method Details

    • init

      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

      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

      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
