Method Detail
-
init
public void init(boolean pEncrypt, CipherParameters pParams)
Description copied from interface:BlockCipher
Initialise the cipher.- Specified by:
init
in interfaceBlockCipher
- Parameters:
pEncrypt
- if true the cipher is initialised for encryption, if false for decryption.pParams
- the key and other data required by the cipher.
-
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 interfaceBlockCipher
-
getAlgorithmName
public java.lang.String getAlgorithmName()
Description copied from interface:BlockCipher
Return the name of the algorithm the cipher implements.- Specified by:
getAlgorithmName
in interfaceBlockCipher
- 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 interfaceBlockCipher
- Returns:
- the block size for this cipher in bytes.
-
processBlock
public int processBlock(byte[] pInput, int pInOff, byte[] pOutput, int pOutOff)
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 interfaceBlockCipher
- Parameters:
pInput
- the array containing the input data.pInOff
- offset into the in array the data starts at.pOutput
- the array the output data will be copied into.pOutOff
- the offset into the out array the output will start at.- Returns:
- the number of bytes processed and produced.
