Been wanting to try implementing a XOR cipher for awhile, a very simple cheap to implment encryption, that actually has a rich history dates back to paper and teletype and world war II (as a one-time pad).
It can be used for anything that can be encoded into a string, be it across the wire, in a shared object, configuration files. It's not high security but it's better than being naked.
In looking around I found on larger strings or XML there were ways to improve the speed. Also I wanted something easy to send across the wire (so pres escaped). It also includes a random string generator for the key.
The AS3 source can be found here on google code XORCipher.as
A sample unit test case is here. It's simple to use:
1 2 3 4 | var xord:String = xor.xor_escape("Hello World"); //String to Xor var xord2:String = xor.xor_unescape(xord); //Xored to plain text String e.g. Hello World |
