How to obtain different cipher text for same plain text using AES

Question

I am currently using AesManaged class in C# to encrypt a plain text. It works fine.

However, it produces the same cipher text each time it encrypts same piece of da

Answer 1

Encryption algorithms have to be deterministic (otherwise there's no way of reversing them)

If you want to get different cipher text, you'll have to change the key, or the data to be encrypted (or the actual algorithm).
