Managing Multiple SSH Keys

README.md

Preparation

• Create different SSH Keys for each account. A simple SSH key can be generated using ssh-keygen -t rsa -C 'email@example.com'
• Create a blank config file and include host details as in provided example file. Add an indentifier to differentiate hosts for similar host names.

Tree structure of ~/.ssh folder

/Users/hadi/.ssh/
├── config
├── id_rsa_example_enterprise
├── id_rsa_example_enterprise.pub
├── id_rsa_example_personal
├── id_rsa_example_personal.pub
├── id_rsa_github
├── id_rsa_github.pub
└── known_hosts

Cloning Repositories

• Clone repositories with the host changed to the one indicated in the config file matching the correct SSH key. For instance, use git clone git@example.com.enterprise:hadi/something.git instead of git clone git@example.com:hadi/something.git

config

Host example.com.enterprise
  HostName example.com
  User git
  IdentityFile ~/.ssh/id_rsa_example_enterprise

Host example.com.personal
  HostName example.com
  User git
  IdentityFile ~/.ssh/id_rsa_example_personal

Host github.com
  HostName gitbub.com
  User git
  IdentityFile ~/.ssh/id_rsa_github
