Software engineers should be made aware of such pitfalls, but I don't think a whole course is necessary or useful. It's very easy to build encryption that you can't crack, especially because the "types of attacks" is a truly endless font.

It's probably more useful to have a module within a course to discuss the current state of the art and learning some history about how the methods were chosen (e.g. NIST's AES, SHA2/3, and PQC open processes. I think making it very obvious that there are extremely good, quality, free tools out there would reduce the likelihood of someone DIYing some crap.

That said, I once spec'd using Ed25519 asymmetric signatures for webhooks sent out to customers, and later on one of our Elixir developers was complaining that the throughput was garbage. I was confused because https://ed25519.cr.yp.to/ boasts signing rates of ~27k/sec/core on very old hardware. Turns out they were using some "pure Elixir" library which had shit (over 1000x worse) performance. There wasn't any real surface area for attacks here, but there are plenty of devs who will blindly search package-manager-of-choice for an otherwise good encryption and get screwed. Not sure who blame in that scenario.
