A problem is //! that the key setup of Arcfour is quite weak, you should never use //! keys with structure, keys that are ordinary passwords, or //! sequences of keys like @expr{"secret:1"@}, @expr{"secret:2"@}, //! ..... If you have keys that don't look like random bit strings, //! and you want to use Arcfour, always hash the key before feeding it //! to Arcfour.
