* DEV: Switch our fast_xor gem for xorcist We use the `xor` function as part of password hashing and we want to use a faster version than the native ruby xor'ing feature so we use a gem for this. fast_xor has been abandoned, and xorcist fixed our initial holdup for switching in https://github.com/fny/xorcist/issues/4 xorcist also has jruby support so we can remove our jruby fallback logic. * Move using statement inside of class
