Registering SSH Keys for GIT Authentication - Video Example
- Eliot Muir
This video shows the quick process one needs to go through for setting up ssh keys to authenticate to a remote GIT host provider, in this case GitHub:
Normally source code is not something that we want anyone to contribute and edit - unless it’s open source. So how do we go about authenticating who is allowed to read and write to the code in a GIT repository?
One convenient means of accessing GIT is via ssh keys. For that you need to generate a public-private key pair.
This is the typical workflow using ssh-keygen which is part of the openssl command line distribution - command line distributions exist for all the major platforms - windows, linux and Mac OS X.
parallels@parallels-Parallels-Virtual-Platform:~$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/parallels/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/parallels/.ssh/id_rsa.
Your public key has been saved in /home/parallels/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:qBFcPXg5kUnu7wVnTGKJ1oZTM+DAMD8WzYko9IN/+tQ parallels@parallels-Parallels-Virtual-Platform
The key's randomart image is:
+---[RSA 2048]----+
| .. o++B+B+ |
| .+.++=%= + |
| ..= +.Bo* . |
| . + = + + |
| o o S . + |
| = . . + |
| o . E . . |
| o . . |
| . . |
+----[SHA256]-----+
You then typically need to take the contents of .ssh/id_rsa.pub (the public key) and add it to a list of known keys under your profile for your git hosting provider like github, Bitbucket etc. The precise interface varies depending on which provider you use.
