How to enable SSH access using a GPG key for authentication
opensource.com/article/19/4/gpg-subkeys-ssh
To do this, specify the
keys
in the ~/.gnupg/sshcontrol file. The entries in this file are keygrips —internal identifiers
gpg
-agent uses to refer to
keys
. Unlike a
key
hash, a keygrip refers to both the public and private
key
. To find the keygrip, use gpg2 -K --with-keygrip, as shown below. Then add that line to the sshcontrol file.

Step 1 — Creating
SSH

. The first step to configure
SSH
key
authentication to your server is to generate an
SSH
