Simple method for creating deterministic passwords on the commandline

This is a simple shell function that uses openssl to create a unique password for any website / service using a master password salt.

Usage:

> pass twitter.com
Password:  
_1vvfamnYcHegiXn0uAL2n1. is now in your clipboard for twitter.com.
>

Your twitter password is now in your clipboard ready to paste.

Install:

Add this function to your .bashrc or .zshrc file. On MacOS replace xclip with pbcopy.

zsh on linux:

pass() { _p=$(openssl passwd -1 -salt $(read -s '_pass?Password: ' && echo $_pass) "$1" | awk -F$ '{print "_1"$NF}') && echo "$_p is now in your clipboard for $1." && echo $_p | xclip -selection clipboard }

bash on linux:

pass() { _p=$(openssl passwd -1 -salt $(read -s -p 'Password: ' _pass && echo $_pass) "$1" | awk -F$ '{print "_1"$NF}') && echo "$_p is now in your clipboard for $1." && echo $_p | xclip -selection clipboard }
