A very simple local password manager

local_pass.sh

#!/usr/bin/sh

pass_file=$HOME/local_pass.gpg
recpt_name='CHANGE_ME'

if [ x"$recpt_name" = x'CHANGE_ME' ]; then
    echo "Change the recpt_name to the email of your secret key"
    exit 1
fi

if [ x"$1" = x'decrypt' ]; then
    gpg --decrypt $pass_file | grep "$2:"
elif [ x"$1" = x'encrypt' ]; then
    echo "Password: "; read -s PASSWORD
    (gpg --decrypt $pass_file && echo $2: $PASSWORD) | \
        gpg --encrypt --armor --recipient $recpt_name --output $pass_file --yes
elif [ x"$1" = x'generate' ]; then
    cat /dev/urandom | base64 | head -c${2:-16}; echo
fi

# USAGE:
#   ./local_pass.sh decrypt USER_NAME
#       This will look through the $pass_file for a string that matches
#       USER_NAME and prints that out.
#
#   ./local_pass.sh encrypt USER_NAME
#       This will add the username: password entry to the $pass_file.
#
#   ./local_pass.sh generate LENGTH
#       This will generate a super-secret and uncrackable password.

Mind you this is a horrendously stupid way to do it, but it works .... kinda.
