java.lang.Object
org.bouncycastle.crypto.paddings.X923Padding
- BlockCipherPadding
public class X923Padding
extends java.lang.Object
A padder that adds X9.23 padding to a block - if a SecureRandom is
passed in random padding is assumed, otherwise padding with zeros is used.
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.
