I would be interested in learning more about such padding systems. I
have done a lot of reading for this development project, and I have
never come across a cryptographic approach to hide length differences by
padding. Of course, padding to the block cipher's block size is already
part of the process, but that is done out of necessity, not because you
want to disguise the length. Are there any other methods? I'm
interested to learn more.
