multiple-ssh

Manage multiple ssh keys on 1 machine

Generate 2 ssh keys:

$ ssh-keygen -t rsa -b 4096 -C "personal@example.com" -f "id_rsa_personal"
$ ssh-keygen -t rsa -b 4096 -C "work@example.com" -f "id_rsa_work"

Modify ssh config file (~/.ssh/config)

Host github.com-personal
  IdentityFile ~/.ssh/id_rsa_personal
  HostName github.com
  User git

Host github.com-work
  IdentityFile ~/.ssh/id_rsa_work
  HostName github.com
  User git

Verify ssh keys

ssh -T git@github.com-personal
ssh -T git@github.com-work

Move to your repository and change config information

$ git config user.name "personal_username"
$ git config user.email "personal@example.com" 
$ git remote set-url origin git@github.com-personal:personal_username/repository-name.git
