The RSA has nothing to do when you use a emulator and client that has the encryption disabled, such as Arcturus. Implement it yourself and change the RSA key. There is (not sure if it still exists) also am exploit in the Diffiehellman when sending w.e. key as a 0.
Sadly tanji is also know to bypass the encryption. Although I haven't looked at it to say how.
I suggest you start with my first few suggestions.
Good luck.
