The cipher Nikola linked to uses SHA1 as a block cipher in OFB mode. Since OFB doesn't require a 'decode' function, it works fine. It seems like it should be secure as long as SHA1 is, but I'm no cryptographer. -Nick On Nov 28, 9:46 am, "Andrew Badera" <[EMAIL PROTECTED]> wrote: > SHA == one-wa

You can try encryption based on the built-in SHA module that is supposed to be implemented in native code: http://www.nightsong.com/phr/crypto/p3.py On Nov 27, 7:22 am, Leonid Evdokimov <[EMAIL PROTECTED]> wrote: > Marzia Niccolai wrote: > > There aren't many pure python implementations for en

Hi Leonid, There aren't many pure python implementations for encryption libraries, for obvious performance reasons. I know of one RSA implementation in pure python (http://stuvel.eu/rsa), though I don't know if the performance of these libraries is such that a request can be made within the App E
