Pick some keyed nonlinear function of 64 bits to 64 bits, then do a 500-round Feistel cipher. It's pretty straightforward to get decent secret-key encryption; the tricky part is doing it quickly. On Sat, Aug 17, 2013 at 7:59 PM, Warren D Smith <warren.wds@gmail.com> wrote:

Any recommended secret-key cryptosystems?
My desiderata are simple+short algorithm and high security level. Speed is not very important.
--I don't think so. The AES implementation here: https://polarssl.org/aes-source-code is 1400 lines long. I repeat, my top priority is simple+short algorithm.
