TEAEngine
public TEAEngine()
Create an instance of the TEA encryption algorithm
and set some defaults
getAlgorithmName
public String getAlgorithmName()
Return the name of the algorithm the cipher implements.
- getAlgorithmName in interface BlockCipher
- the name of the algorithm the cipher implements.
getBlockSize
public int getBlockSize()
Return the block size for this cipher (in bytes).
- getBlockSize in interface BlockCipher
- the block size for this cipher in bytes.
init
public void init(boolean forEncryption,
CipherParameters params)
initialise
- init in interface BlockCipher
forEncryption
- whether or not we are for encryption.params
- the parameters required to set up the cipher.
processBlock
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.
- processBlock in interface BlockCipher
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.
- the number of bytes processed and produced.
reset
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).
- reset in interface BlockCipher
