Putty keys inside of MSYS2
For a long time, I had separate private keys for putty and for msys2. This was purely because I never found time to figure out how I could make the keys loaded in putty (through
pagent.exe) available to the msys2 environment.
A fewy days ago, I finally found myself desperate enough to start investigating this issue.
It turns out that it’s super easy to achieve as somebody already occupied him or herself with this task: Enter cuviper’s ssh-pagent scripts.
ssh-pageant works like
ssh-agent, except that it leaves the key storage to PuTTY’s Pageant. It sets up an authentication socket and prints the environment variables, which allows OpenSSH connections to use it.
Things get even easier: There’s a ready-to-go package for MSYS2 that can be installed out of the box:
pacman -S ssh-pageant
After installation, add the following to your
# ssh-pageant eval $(/usr/bin/ssh-pageant -r -a "/tmp/.ssh-pageant-$USERNAME")
And that’s it!
