Module Crypto.RC4

Description

RC4 is a stream cipher, sometimes refered to as Arcfour, and while very fast isn't considered secure anymore.

Note

The key setup of RC4 is quite weak, so you should never use keys with structure, such as ordinary passwords. If you have keys that don't look like random bit strings, and you want to use RC4, always hash the key before feeding it to RC4.

The first few thousand bits have a slight bias, so it is not uncommon for applications to encrypt a few kilobytes of dummy data before actual encryption.
