简单的javascript加密,对url查询是安全的

var jsEncode = {
  encode: function(s, k) {
    var enc = "";
    var str = "";
    // make sure that input is string
    str = s.toString();
    for (var i = 0; i < s.length; i++) {
      // create block
      var a = s.charCodeAt(i);
      // bitwise XOR
      var b = a ^ k;
      enc = enc + String.fromCharCode(b);
    }
    return enc;
  }
};


var code = '1';
var e = jsEncode.encode("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ123456789@,.-", code);
console.log(e);
var d = jsEncode.encode(e, code);
console.log(d);
