A couple years back we wrote a guide on how to create good OpenPGP/GnuPG keys and now it is time to write a guide on SSH keys for much of the same reasons: SSH key algorithms have evolved in past years and the keys generated by the default OpenSSH settings a few years ago are no longer considered state-of-the-art. This guide is intended both for those completely new to SSH and to those who have already been using it for years and who want to make sure they are following the latest best practices.
