There may come a time when you want to confirm the validity of the SSH keys you are using or about to use.
This might help with troubleshooting or even for an on-the-fly security audit.
You can check all available keys on the machine with the following command:
for key in ~/.ssh/id_*; do ssh-keygen -l -f "${key}"; done | uniq
You can also just go down to the .ssh folder with
cd .ssh && ls -al
or if you are on a different path:
cd ~/.ssh && ls -al
Now run:
ssh-keygen -l -f $keyname ssh-keygen -l -f $keyname.pub
