Modifier and Type | Method | Description |
---|---|---|
int |
getInputBlockSize() |
returns the largest size an input block can be.
|
int |
getOutputBlockSize() |
returns the maximum size of the block produced by this cipher.
|
void |
init(boolean forEncryption,
CipherParameters param) |
initialise the cipher.
|
byte[] |
processBlock(byte[] in,
int inOff,
int len) |
process the block of len bytes stored in in from offset inOff.

void init(boolean forEncryption, CipherParameters param)
forEncryption
- if true the cipher is initialised for
encryption, if false for decryption.param
- the key and other data required by the cipher.int getInputBlockSize()
int getOutputBlockSize()
byte[] processBlock(byte[] in, int inOff, int len) throws InvalidCipherTextException
in
- the input datainOff
- offset into the in array where the data startslen
- the length of the block to be processed.InvalidCipherTextException
- data decrypts improperly.DataLengthException
- the input data is too large for the cipher.
