    • init

      public void init(boolean forSigning, CipherParameters param)
      Description copied from interface: Signer
      Initialise the signer for signing or verification.
      Specified by:
      init in interface Signer
      Parameters:

      param - necessary parameters.

    • generateSignature

      public byte[] generateSignature(byte[] message)

    • verifySignature

      public boolean verifySignature(byte[] message, byte[] signature)

    • update

      public void update(byte b)
      Absorb a byte of the message to be signed or verified. The buffered message is consumed by generateSignature() / verifySignature(byte[]), which reset the buffer.
      Specified by:
      update in interface Signer

    • update

      public void update(byte[] in, int off, int len)
      Description copied from interface: Signer
      update the internal digest with the byte array in
      Specified by:
      update in interface Signer

    • generateSignature

      public byte[] generateSignature()
      Description copied from interface: Signer
      generate a signature for the message we've been loaded with using the key we were initialised with.
      Specified by:
      generateSignature in interface Signer

    • verifySignature

      public boolean verifySignature(byte[] signature)
      Description copied from interface: Signer
      return true if the internal state represents the signature described in the passed in array.
      Specified by:
      verifySignature in interface Signer

    • reset

      public void reset()
      Description copied from interface: Signer
      reset the internal state
      Specified by:
      reset in interface Signer
