Multiple SSH Keys

create different public key

create different ssh key, Git Bash on Windows / GNU/Linux / macOS:

$ ssh-keygen -t rsa -C "your_email@youremail.com"

copy key macOS:

$ pbcopy < ~/.ssh/<name>.pub

or GNU/Linux (requires the xclip package):

$ xclip -sel clip < ~/.ssh/<name>.pub

or Windows Command Line:

$ type %userprofile%\.ssh\<name>.pub | clip

Git Bash on Windows / Windows PowerShell:

$ cat ~/.ssh/<name>.pub | clip

for example, 2 keys created at:

~/.ssh/id_rsa_activehacker
~/.ssh/id_rsa_jexchan

then, add these two keys as following

$ ssh-add ~/.ssh/id_rsa_activehacker
$ ssh-add ~/.ssh/id_rsa_jexchan

you can delete all cached keys before

$ ssh-add -D

finally, you can check your saved keys

$ ssh-add -l

Modify the ssh config

$ cd ~/.ssh/
$ touch config
$ subl -a config

Then added

#activehacker account
Host github.com-activehacker
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_activehacker

#jexchan account
Host github.com-jexchan
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_jexchan

Clone you repo and modify your Git config

then use normal flow to push your code

$ git config user.name "activehacker"
$ git config user.email "jexlab@gmail.com" 
$ git add .
$ git commit -m "your comments"
$ git push
