| BlockCipher | | public interface BlockCipher (Code) | | Block cipher engines are expected to conform to this interface.

| Method Summary | |
| public String | getAlgorithmName()
Return the name of the algorithm the cipher implements. | | public int | getBlockSize()
Return the block size for this cipher (in bytes). | | public void | init(boolean forEncryption, CipherParameters params)
Initialise 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.
Parameters:
inOff - offset into the in array the data starts at.
Parameters:
out - the array the output data will be copied into.
Parameters:
outOff - the offset into the out array the output will start at.
exception:
DataLengthException - if there isn't enough data in in, orspace in out.
exception:
IllegalStateException - if the cipher isn't initialised. | | public void | reset()
Reset the cipher. |
| getAlgorithmName | | public String getAlgorithmName()(Code) | | Return the name of the algorithm the cipher implements.
the name of the algorithm the cipher implements. |
| getBlockSize | | public int getBlockSize()(Code) | | Return the block size for this cipher (in bytes).
the block size for this cipher in bytes. |
| init | | public void init(boolean forEncryption, CipherParameters params) throws IllegalArgumentException(Code) | | Initialise the cipher.
Parameters:
forEncryption - if true the cipher is initialised forencryption, if false for decryption.
Parameters:
params - the key and other data required by the cipher.
exception:
IllegalArgumentException - if the params argument isinappropriate. |
| processBlock | | public int processBlock(byte[] in, int inOff, byte[] out, int outOff) throws DataLengthException, IllegalStateException(Code) | | Process one block of input from the array in and write it to
the out array.
Parameters:
in - the array containing the input data.
Parameters:
inOff - offset into the in array the data starts at.
Parameters:
out - the array the output data will be copied into.
Parameters:
outOff - the offset into the out array the output will start at.
exception:
DataLengthException - if there isn't enough data in in, orspace in out.
exception:
IllegalStateException - if the cipher isn't initialised. the number of bytes processed and produced. |
| reset | | public void reset()(Code) | | Reset the cipher. After resetting the cipher is in the same state
as it was after the last init (if there was one).
