How to run (git/ssh) authentication agent?

If you're using Msysgit, you can find a good tutorial here: http://anterence.blogspot.com/2012/01/ssh-agent-in-msysgit.html

1. Add a file called .bashrc to your home folder

2. Open the file and paste in:

   #! /bin/bash 
   eval `ssh-agent -s` 
   ssh-add
   

3. This assumes that your key is in the conventional ~/.ssh/id_rsa location. If it isn't, include a full path after the ssh-add command.

4. Add to or create file ~/.ssh/config with the contents

   ForwardAgent yes
   

   In the original tutorial the ForwardAgent param is Yes, but it's a typo. Use all lowercase or you'll get errors.

5. Restart Msysgit. It will ask you to enter your passphrase once, and that's it (until you end the session, or your ssh-agent is killed.)

[EDIT] If you don't want to start a new ssh-agent every time you open a terminal, check out Keychain. I'm on a Mac now, so I used this tutorial to set it up, but I'm sure a Google search will have plenty of info for Windows.
