My passwords here at Mozilla are basically pretty long and I use mutt as a mailer, so it gets rather tedious whenever I send out an email to type in my password each time. So I spent some time setting up gpg-agent on my system and gpg encrypted a file that contains my password. This blog post will document the method used to achieve this setup

Installing GPG and gpg-agent

Depending on your OS you will need to have gnupg and gpg-agent installed, I'm running Mac OSX so I used homebrew

brew install gnupg
brew install gpg-agent

Encrypting password file

I created a gpg encrypted password file in my home directory

mkdir -p ${HOME}/.passwd
echo "My password" | gpg -r <email here> --encrypt > ~/.passwd/mozilla.gpg

Setting up bash

Create the a file called .bash_gpg in your home directory


if test -f "$envfile" && kill -0 $(grep GPG_AGENT_INFO "$envfile" | cut -d: -f 2) 2>/dev/null; then
    eval "$(cat "$envfile")"
    eval "$(gpg-agent --daemon --log-file=~/.gpg/gpg.log --write-env-file "$envfile")"
export GPG_AGENT_INFO  # the env file does not contain the export statement

Add the following to your .bashrc file

GPG_AGENT=$(which gpg-agent)
export GPG_TTY

if [ -f ${GPG_AGENT} ]; then
    . ~/.bash_gpg

You can further configure the nature of gpg-agent by editing the ~/.gnupg/gpg-agent.conf file

default-cache-ttl 86400
pinentry-program /usr/local/bin/pinentry
max-cache-ttl 172800

Thats just an example of what I have, of course you can edit it to suit your needs
