The `ssh-keygen` command is not installed in Arch Linux and can't find it in AUR or official packages

As the title says.

For some reason ssh-keygen is not installed on my install of Arch Linux, and I can't seem to find it on the AUR or the official packages repository.

How would I go about obtaining it?

The ArchWiki assumes you have it installed and doesn't give instructions on how to install it: https://wiki.archlinux.org/index.php/SSH_Keys

Or at least it doesn't make it obvious. If I missed it please say so. :)

Any help is appreciated. :)

The ssh-keygen command is part of OpenSSH (package "openssh"). That's why the article assumes you have it installed – you wouldn't be able to use ssh if you didn't.

Use pkgfile (-v) or pacman -Fs to find which packages contain a given file:

$ sudo pkgfile -u
$ pkgfile -v ssh-keygen
core/openssh 7.2p2-1        /usr/bin/ssh-keygen

$ sudo pacman -Fy
$ pacman -Fs ssh-keygen
core/openssh 7.2p2-1
    usr/bin/ssh-keygen
