hello there

i wonder if anyone can assist me. I am trying to write a secure payment midlet (MIDP 1.0) to simulate SSL (Triple DES). I have made use of the bounycastle cryptology API (DESEngine()) to encrypt the credit card information however i am POSTin this encrypted data to a C# .NET ASP.NET .aspx page but am unable to decrypt as the initialization vectors and legal key and block sizes are different? does anyone have a solution for this or some code that performs transfer of secure credit card information? what other lightweight cryptology APIs can one use? how does the gaming ferternity handle payment for midlet games?
anything will be greatly appreciated
