It's possible this is the wrong way to get AES on the command-line; I haven't done it and no need to right now. But that's missing my point entirely.

Your point is that you can do the wrong thing with OpenSSL so that means you don't need a tool that does the right thing?

That is not a solid point.

The point being?

You've linked to a command that's wrong, from a random internet "everybody gets to answer a question and everybody gets to vote for the best answer, no qualifications required" website, and wrote "with that I'm guaranteed AES, a known-good encryption algorithm" as if that means anything.
