    • Method Detail

      • getReductionPolynomial

        protected static long getReductionPolynomial​(int blockSize)

      • getOutputSize

        public int getOutputSize​(int length)
        Description copied from class: BufferedBlockCipher
        return the size of the output buffer required for an update plus a doFinal with an input of 'length' bytes.
        Overrides:
        getOutputSize in class BufferedBlockCipher
        Parameters:
        length - the length of the input.
        Returns:
        the space required to accommodate a call to update and doFinal with 'length' bytes of input.

      • getUpdateOutputSize

        public int getUpdateOutputSize​(int len)
        Description copied from class: BufferedBlockCipher
        return the size of the output buffer required for an update an input of len bytes.
        Overrides:
        getUpdateOutputSize in class BufferedBlockCipher
        Parameters:
        len - the length of the input.
        Returns:
        the space required to accommodate a call to update with len bytes of input.

      • init

        public void init​(boolean forEncryption,
                 CipherParameters parameters)
        Description copied from class: BufferedBlockCipher
        initialise the cipher.
        Overrides:
        init in class BufferedBlockCipher
        Parameters:
        forEncryption - if true the cipher is initialised for encryption, if false for decryption.
        parameters - the key and other data required by the cipher.

      • processByte

        public int processByte​(byte in,
                       byte[] out,
                       int outOff)
        Description copied from class: BufferedBlockCipher
        process a single byte, producing an output block if necessary.
        Overrides:
        processByte in class BufferedBlockCipher
        Parameters:
        in - the input byte.
        out - the space for any output that might be produced.
        outOff - the offset from which the output will be copied.
        Returns:
        the number of output bytes copied to out.

      • processBytes
