What is the public URL for the Github public keys
GitGithubBitbucketPublic KeyGit Problem Overview
I heard that there was a public URL for all users on github where you can access their public keys or they can supply that URL of all their public keys. Is this true? If so what is that URL. Does it exist for bitbucket as well?
Git Solutions
Solution 1 - Git
You can get with:
curl https://github.com/<username>.keys
Replace <username> with the actual username of the GitHub user.
This is useful when you set login permission to other servers. Just save its output into ~/.ssh/authorized_keys. To append it to the end from the command line:
curl https://github.com/<username>.keys | tee -a ~/.ssh/authorized_keys
It can also be done using Github API
curl -i https://api.github.com/users/<username>/keys
For bit bucket you can use the following: (This call requires authentication.)
curl -i https://bitbucket.org/api/1.0/users/<accountname>/ssh-keys
Solution 2 - Git
GPG public keys are now available at https://github.com/<username>.gpg
Solution 3 - Git
Works for gitlab same way too.
https://gitlab.com/<username>.keys
Works nicely in bash scripts too.
#GitProvider to fetch public keys (gitlab.com,github.com)
GitProvider="gitlab.com"
GitUsername="username"
curl https://${GitProvider}/${GitUsername}.keys | tee -a ~/.ssh/authorized_keys
Solution 4 - Git
In addition these also provide a way to retrieve a user's PGP keys:
GitHub:
https://github.com/USER.keys
https://gitlab.com/USER.gpg
GitLab:
https://gitlab.com/USER.keys
https://gitlab.com/USER.gpg
Solution 5 - Git
While the keys are public you don't always want to reveal your internal hostnames from the default comment fields, so I'd recommend ssh-copy-id command if you have SSH password access, wormhole when on console and configuration management tools (like Ansible, Puppet etc) in the first place.
