RE: [phplib] Encryption function From: Allen Lee (alee <email protected>)

Look at http://www.counterpane.com/solitaire.html

Solitaire is an output feedback mode cipher - a reversible encryption
function that can be demonstrated with a deck of cards.

It is simple enough to do by hand, but is "secure even against the most
well-funded military adversaries with the biggest computers and the smartest
cryptanalysts."

There is a downloadable perl script at http://www.counterpane.com/sol.pl
that u can run as a cgi (or convert to php)

If you convert to php, can I have a copy?

Subject: [phplib] Encryption function

Hi all,

I just wondering is there any function like md5() or sort of that can do
switch back? I mean

if I use md5("secret") produce let say 1234
from that 1234 I can tell that is "secret" string

My Uni. PHP doesn't support encryption ie. no --with-mycrypt

so I have to do my own encryption.... Any suggestion? any free function that
I can use?

Thanks,
Irvan
