hi guyz!!! I have a problem here...I have 2 windows application 1 was developed using VB6(not VB.net) and the other using c#.net and they both capable of querying and sending data from/to the database server(MSSQL 2005) my problem is how can I encrypt the data from one windows application(VB6) where in when i try to decrypt it to other windows application(c#.net) it would still give me the original text. Btw, i want the encryption/decryption to happen in the application not in the database server since i dont want to send it to the server in a clear text. any suggestion? thanks in advance!!!
