public class TBCPadding extends Object implements BlockCipherPadding
This padding pads the block out with the compliment of the last bit of the plain text.
Method Summary | |
---|---|
int | addPadding(byte[] in, int inOff)
add the pad bytes to the passed in block, returning the
number of bytes added.
|
String | getPaddingName()
Return the name of the algorithm the padder implements.
|
void | init(SecureRandom random)
Initialise the padder.
|
int | padCount(byte[] in)
return the number of pad bytes present in the block. |
Note: this assumes that the last block of plain text is always passed to it inside in. i.e. if inOff is zero, indicating the entire block is to be overwritten with padding the value of in should be the same as the last block of plain text.
Returns: the name of the algorithm the padder implements.
Parameters: random - a SecureRandom if available.
