parole

Very simply CLI password generator. This has probably been done a trillion times already. However, here's the one I occasionally use.

What it does

Generates a password by invoking parole and copies it to the clipboard (if supported on your system).

Installation

Install via pypi:

pip install parole --upgrade

Simply install from Github itself via:

pip install "git+ssh://git@github.com/merschformann/parole.git" --upgrade

Usage

Generate and copy a password with default characteristics via:

parole

Generate, copy and display a password (make sure you're the only reader):

parole -s

Display help:

parole --help

Get a password of specific length and alphabet via:

parole --alphabet "a!" --uppercase --digits --length 10

Resulting alphabet of this example is aABCDEFGHIJKLMNOPQERSTUVWXYZ1234567890!. This is the result of combining the explicitly given symbols 'a' & '!', all uppercase latin letters [A-Z] and all digits [0-9].

Copy to clipboard

The generator uses pyperclip for copying the password to the clipboard. The authors of pyperclip did great work of supporting multiple platforms. However, if you run into problems, please consult the docs of the package: https://pypi.org/project/pyperclip/

On Linux a package to support terminal copy to clipboard is needed. I usually install xsel, e.g.:

sudo apt install xsel

Why?

I use it for quickly generating a password while on the terminal (potentially using a custom alphabet). Furthermore, for myself it was a similar effort as googling a reliable and somewhat cryptographically secure solution. I am no expert on the latter, but I trust the authors of the secrets module (see https://docs.python.org/3/library/secrets.html#module-secrets).
