Fetches a GitHub user's public SSH key(s) via the GitHub API
|

User can be given as first argument, otherwise falls back to using environment variables \$GITHUB_USER or \$USER
|
|
|
|
SSH Keys can be found in the Web UI here:
|

|
https://github.com/settings/keys
|
|

To retrieve SSH keys with comments, you'd need to use API authentication, see
