The private/public key pairs are usually stored in the user's home directory under the (invisible) directory .ssh/.

The default file names where the private/public key pairs are stored are

- id_rsa

- id_rsa.pub

Procedure:

[bash]~ >cd ~/.ssh
[bash]~/.ssh > ssh-keygen -t rsa -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/username/.ssh/id_rsa): 
/home/username/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/username/.ssh/id_rsa.
Your public key has been saved in /home/username/.ssh/id_rsa.pub.
The key fingerprint is:
11:8[...]:f1:a5 [email protected]
The key's randomart image is:
+--[ RSA 2048]----+
| o+. =+.=%|
[ ...] 
+-----------------+ 
[bash]~/.ssh >ssh-add id_rsa
Enter passphrase for id_rsa: 
Identity added: id_rsa (id_rsa)

##Add SSH keys to GitLab/GitHub SSH keys [back to top]

Copy the content from id_rsa.pub and add them to the SSH keys on GitHub/GitLab.

e.g.,

ssh-rsa AA[...]== [email protected]	

[back to top]

Replace the example information in the following lines and add them to the .ssh/config file:

Host GitLab.uni.edu
HostName GitLab.uni.edu
IdentityFile ~/.ssh/id_rsa
User username

Create new repository on GitHub/GitLab:

then change the global Git settings:

[bash]~/Gits >bash]~/ > git config --global user.name "rasbt"
[bash]~/Gits >bash]~/ > git config --global user.email "[email protected]"

Now, you can clone the new repository to your local drive:

[bash]~/ >cd github_repos
[bash]~/github_repos/ >git clone [email protected]:rasbt/github_reference.git
