But why salsa20 in that case, unless it's approved as a standard?  If
you're willing to put up with terrible performance in the fallback
implementation, you may as well use AES, which is a standard.  If you
want reasonable performance in the fallback implementation, use
one of the hashlib functions as a cipher.
