Public Constructors

public SEEDEngine ()

Public Methods

public String getAlgorithmName ()

Return the name of the algorithm the cipher implements.

Returns
  • the name of the algorithm the cipher implements.

public int getBlockSize ()

Return the block size for this cipher (in bytes).

Returns
  • the block size for this cipher in bytes.

public void init (boolean forEncryption, CipherParameters params)

Initialise the cipher.

Parameters
forEncryption if true the cipher is initialised for encryption, if false for decryption.
params the key and other data required by the cipher.

public int processBlock (byte[] in, int inOff, byte[] out, int outOff)

Process one block of input from the array in and write it to the out array.

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.

public void reset ()

Reset the cipher. After resetting the cipher is in the same state as it was after the last init (if there was one).
