view your ssh public key's fingerprint; compare this to what Github has listed in the ssh key audit

key-fingerprint

$ ssh-keygen -l -f /path/to/keys/id_rsa.pub
2048 aa:bb:cc:dd:ee:ff:00:11:22:33:44:55:66:77:88:99 id_rsa.pub (RSA)

yup, it'll probably be ~/.ssh

edited the gist to be a little more clear.

ssh-keygen -lv # displays pretty ASCIIart
ssh-keygen -B # displays easy to memorize gobbledigook

thank you!
wish github had this instruction on the verify ssh keys page (https://github.com/settings/ssh)

@sujee e.g.
ssh-keygen -l -f ~/.ssh/id_rsa.pub

nice one +1

With newer versions of ssh
ssh-keygen -l -E md5 -f ~/.ssh/my-github-key.pub

Thanks @jamesp9

If you are using something like a Yubikey, where there isn't necessarily a file to check, the ssh-add command takes an argument to change the fingerprint algorithm.

This outputs fingerprints in the format that GitHub displays:

ssh-add -l -E md5

On MacOS I used the following to get the fingerprint as shown in github

> ssh-keygen -l -E md5 -f id_ed25519.pub                                                                                                                                                                          ⏎
