how to get over security in asp.net

Question

If you have a code, log in information of which is encrypted, how to decrypt using asp.net ?

Cryptography class?

Any other?

Answer 1

As it stands, I think you need to add more information to answer your question more effectivly.

However, ASP.NET Forms Authentication is the normal way to acheive this. Typically one would use HTTPS to secure communication between client and server.
