help encrypt/decrypt C#.NET and VB6

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!!!

I know you'll have to use a "single key algorithm" to encrypt/decrypt your text (e.g DES)
use the same key in both Applications and there must be no problems

Thanks! but i want the encryption/decryption to happen in my application before i send/received it from/to MSSQL server...any suggestions...

hello...any inputs?please help me..i'm desperately looking for a encryption and decryption solution that works perfectly with C#.net and VB6 take note please VB6 not VB.net...any inputs will be greatly appreciated.

Write a COM library in VB6 and reference it in C#, otherwise write it in C# and read up on how to use .NET libraries in COM applications.

Thanks but...can you give me a link to a tutorial on how to creat a com in VB6? thanks again.
