I'm relatively deep in this stuff. If you asked my how to use the openssl CLI for anything other than X.509 and s_client I would fail your interview.

  Yeah openssl CLI is so incomprehensible. And some parameters have to be configured using .conf files, ewww. The C API is hardly any better. When I read the RFCs behind the stuff to write what I needed in Rust, suddenly it dawned on me: wow this stuff isn't nearly as complicated and horrible as openssl's interface makes it seem like.

  I didn't expect the knowledge of the cli to do it immediately, this person didn't even know they could do it. "openssl dgst -sha256 filename". An answer that they'd need to check the man page would've been sufficient...

    Would you have accepted a python solution? I typically don't do this type of stuff using raw openssl on the rare occasion I need it.

      I would have accepted even the person knowing and confirming they were aware SHA1 is obsolete
