Multiple SSH Keys

Managing multiple SSH keys for Github and Visual Studio Online

Posted on May 2, 2018

After generating a new key for my Visual Studio Online code repository I have to tell git which key to use for each connection.

Create a file in ~/.ssh/config

Add the following content

# Uncomment to enable debugging.
# Levels are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3.
# LogLevel DEBUG

Host ssh.dev.azure.com
    IdentityFile ~/.ssh/id_rsa_visualstudio

Host vs-ssh.visualstudio.com
    IdentityFile ~/.ssh/id_rsa_visualstudio

Host github.com
    IdentityFile ~/.ssh/id_rsa_github

# tell ssh-agent to not try keys
Host *
    IdentitiesOnly yes

#ssh #git #github #visual studio online

How to authenticate to github using SSH keys

Posted on February 23, 2018

The complete instruction on Github

Create a key in the default location without any passphrase (or add one if you like). Then add it to the ssh-agent.

ssh-keygen -t rsa -b 4096 -C "[email protected]"
ssh-add ~/.ssh/id_rsa

Copy the key into the clipboard

cat ~/.ssh/id_rsa.pub

Go into your profile and select SSH and GPG keys, click Add SSH key, add a description and paste the key.

#ssh #github
