I said i compress with AES-256

To avoid confusion you could say, “along with”, or fully say, “I encrypt with AES-256 as I compress, in one step”.

It’s not necessarily about what you know, but about what readers will understand. (For example, someone who doesn’t know better might read what you wrote and think there is some way to compress using AES-256 and go down a rabbit hole.)
