The BlockFormatterEngine interface formats input by inserting
padding into the data. This interface allows for block ciphers that use specific forms of padding.
The BlockUnformatterEngine removes specific padding
from data.

int |
formatAndEncrypt(byte[] input,
int inputOffset,
int inputLength,
byte[] output,
int outputOffset)
Formats the input into the proper format and then encrypts it, assuming this is not the last block to be encrypted. |
|
int |
formatAndEncrypt(byte[] input,
int inputOffset,
int inputLength,
byte[] output,

String |
getAlgorithm()
Returns the name of this algorithm, eg "PKCS5". |
|
int |
getInputBlockLength()
Returns the length of an input block in bytes. |
