Thank you for your suggestion. Take a look if you can to the crypt() function, I use on top of a modified version of RC4 the use of 1 byte initialization vector to further fuzz information (the iv is trasmitted with the string). I am not so much into cryptoanalysis so, I really should have some suggestion in this case.
