Wait, is there really a utility called keyqen? Sounds weird.

I think "ssh-keygen" is definitely the right tool, but I might confuse it with other commands I studied.

I have a vague memory of "keygen" being part of the answer, but I can't remember if it was the right one for SSH specifically.

I remember practicing with SSH, and I feel like "ssh" was involved, but I can't recall if it creates keys or just connects.

I think the utility for creating key pairs is something like "ssh-keygen," but I'm not sure about the exact spelling.
