After you have uploaded your SSH public key to websites like GitHub, they won’t show the complete key anymore - but instead show the key’s fingerprint. This is how you can calculate the fingerprint yourself (e.g. to compare them):
-l stands for “Show the fingerprint”,
-f <filename> for specifiying a file.
This works with both the public as well as the private part of the key. 🔐
GitHub does display complete public key - but not in the settings screen, but on
https://github.com/<USERNAME>.keys 🤯 So, you can find e.g. my public keys here: https://github.com/markusdosch.keys
I learned this through the examples in the Ansible docs on the ansible.posix.authorized_key module.
