E-HACK's WilterCrypt v1.0

Ok, here's WilterCrypt v1.0 a JavaScript crypto-system, its fairly weak, and only allows keys from 1 to 63 and only allows the following charicters:
0123456789abcdefghijklmnopqrstuvwxyz._~ABCDEFGHIJKLMNOPQRSTUVWXYZ
This script really needs some improvement, v1.1 and 1.2 are a little better in that they allow spaces, but the number of charicters is still really low, and the method of encryption (basically a weak XOR) isn't very strong (and the number of keys makes it no trouble to crack) I hope v2.0 will be much more secure and allow for letters to be used in the key, and be a much stronger overall encryption method, but I still need to learn more about cryptography and JavaScript before I'll be able to do that(I've been messing around with other methods of encryption and should have one fairly soon). Well, have fun,
Thanks,
E-HACK
