#15 closed enhancement (duplicate)

Description (last modified by zooko)

Salsa20 is a stream cipher design by Daniel J. Bernstein that is ​significantly more efficient and ​perhaps safer than AES.

On the other hand, it might not turn out to be safer than AES.

Here's a patch (not very much tested, I think), which adds Salsa20 to pycryptopp.

By the way, DJB's ChaChaCha is almost certainly slightly safer and certainly slightly faster than his Salsa20, but Crypto++ doesn't implement ChaChaCha yet.

Oh, we should use XSalsa20 instead of Salsa20. (The same but with a bigger IV -- I think 256-bit instead of a 64-bit IV.)
