The BlockUnFormatterEngine interface removes any formatting from
data.
The BlockFormatterEngine interface applies formatting to
data in the form of extra padding.
| Method Summary | ||
|
int |
decryptAndUnformat(byte[] input,
int inputOffset,
byte[] output,
int outputOffset)
Decrypts the input and then "unformats" it into the original plaintext assuming this block is not the last block in the stream. |
|
int |
decryptAndUnformat(byte[] input,
int inputOffset,
byte[] output,
int outputOffset,
boolean lastBlock)
Decrypts the input and then "unformats" it into the original plaintext. |
|
String |
getAlgorithm()
Returns the name of the signing algorithm used, eg "PKCS5". |
|
int |
getInputBlockLength()
Returns the length of an input block in bytes. |
