davidblewett / lp-ssh-add.sh
Last active December 12, 2021 11:12
Allow storage of SSH private keys in LastPass, and use lpass CLI to retrieve and load into ssh-agent. The general idea is to store the private key armored ASCII in an "SSH Key" Secure Note, in a specific folder (i.e.: "Secure Notes\SSH" ).
#!/bin/sh
#
# Import all SSH keys from LP
#
PREFIX=~
SSH_ASKPASS=$PREFIX/bin/lp-askpass.sh
export SSH_ASKPASS
# This is needed to force ssh-add to honor our SSH_ASKPASS.
DISPLAY=foo
export DISPLAY
