Read the link, really interesting. There's a tiny mistake there tho, on the example. 97 + 112 does not equal 224, no matter what. I was coding a PERL script to decrypt the passwords, and I took the 'pa' '74E0' example, since I was a bit lazy to code a "crypter". Well, here's a PERL script that will decode the password, email me if you can improve it, or if you find any errors (Im pretty sure it has, it's pretty ugly).
