    XOR Cipher

A simple XOR cipher in 95 bytes.
"In cryptography, the simple XOR cipher is a type of additive cipher... a string of text can be encrypted by applying the bitwise XOR operator to every character using a given key. To decrypt the output, merely reapplying the XOR function with the key will remove the cipher."

var xor = function(a,b){return a.replace(/./g,function(a){return String.fromCharCode(a.charCodeAt()^b)})}
