Class CamelliaLightEngine

  • All Implemented Interfaces:
    BlockCipher

    public class CamelliaLightEngine
    extends Object
    implements BlockCipher
    Camellia - based on RFC 3713, smaller implementation, about half the size of CamelliaEngine.

    • Method Detail

      • getAlgorithmName

        public String getAlgorithmName()
        Description copied from interface: BlockCipher
        Return the name of the algorithm the cipher implements.
        Specified by:
        getAlgorithmName in interface BlockCipher
        Returns:
        the name of the algorithm the cipher implements.
      • getBlockSize

        public int getBlockSize()
        Description copied from interface: BlockCipher
        Return the block size for this cipher (in bytes).
        Specified by:
        getBlockSize in interface BlockCipher
        Returns:
        the block size for this cipher in bytes.
      • init

        public void init​(boolean forEncryption,
                         CipherParameters params)
        Description copied from interface: BlockCipher
        Initialise the cipher.
        Specified by:
        init in interface BlockCipher
        Parameters:
        forEncryption - if true the cipher is initialised for encryption, if false for decryption.
        params - the key and other data required by the cipher.
      • processBlock

        public int processBlock​(byte[] in,
                                int inOff,
                                byte[] out,
                                int outOff)
                         throws IllegalStateException
        Description copied from interface: BlockCipher
        Process one block of input from the array in and write it to the out array.
        Specified by:
        processBlock in interface BlockCipher
        Parameters:
        in - the array containing the input data.
        inOff - offset into the in array the data starts at.
        out - the array the output data will be copied into.
        outOff - the offset into the out array the output will start at.
        Returns:
        the number of bytes processed and produced.
        Throws:
        IllegalStateException - if the cipher isn't initialised.
      • reset

        public void reset()
        Description copied from interface: BlockCipher
        Reset the cipher. After resetting the cipher is in the same state as it was after the last init (if there was one).
        Specified by:
        reset in interface BlockCipher
