in thread Safe symmetric encryption - Crypt::CBC + Crypt::Blowfish?

A Block cipher in CBC mode allows you to reuse the key. A Stream cipher is no different than a one-time pad in this respect. RC4 is a stream cipher. Think of a stream cipher as a condensed instruction on how to generate the one-time pad. The key is just a seed for a pseudo-random number generator.
