I have seen many questions on security stack exchange and /r/crypto where the correct answer should have been "use age", but because it didn't exist the correct answer was something bad. openssl CLI is not meant to be used in prod (both because not AEAD and because the man page tells you not to use it). gpg is bad. rolling your own CLI tool using libsodium is not for everyone.

  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.

    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.

      Ok, for the thick-headed: my point is I'll use AES. Good luck with your toy project. Also authenticated encryption is not something I want all the time. I don't always want an identity tied to cipher text, even if the identity is anonymous.

        Authenticated encryption has nothing to do with identity; you've confused message authentication with signatures.

        >Ok, for the thick-headed: my point is I'll use AES. Good luck with your toy project. "AES" without specific qualifications and with instructions sourced from Stack Overflow is an ad-hoc toy project. Age, on the other hand, is a well specified, approved by several domain experts, best-practices project. In the end you can do whatever, but don't use some custom solution ("AES" or not) for anything where human lives or money might depend on. >Also authenticated encryption is not something I want all the time. I don't always want an identity tied to cipher text, even if the identity is anonymous. Identity is not what "authenticated encryption" is about. It's about protecting about certain classes of cipher-text attacks, which people (bad people, one would assume) can use to get information about your encryption.

    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.
