Hello, my name is Javier,
I have seen your project regarding the implementation of a javascript code based on an actionscript code. I have studied the file to convert and I can do it in one day.
The actionscript code implements many methods but I am not sure if you are interested in all of them. We can find the methods encrypt, decrypt, initialize, calculate, charsToHex, hexToChars, charsToStr and strToChars in the code, but I suppose that you will only need the encrypt and decrypt methods, am I correct?
I can do this project for you and check that my algorithm produces the same input/output pairs as the actionscript algorithm for both methods: encrypt and decrypt.
If you are interested in having my services or you like to make any question just let me know.
Thank you for your time reading my proposal!
Javier
