Encode and Decode a string in c#

Question

Hii, I had a requirement of encode a string provided to a unreadable format and also have to decode after certain action performed. I have tried 'Base64' encoding. But this is not a secure way. I need some other solutions. Give some help regarding the above context.

Answer 1

You could use a symmetric encryption algorithm. Here's an example. Both sides (encrypt/decrypt) must share a common secret key for this to work.
