pwdgen

A simple password generator for the command line.

Features

• The password is generated using a cryptographically secure pseudo-random number generator (CSPRNG).
• Unlike popular password generator websites, this app runs on your machine and will never send anything over the network.
• A small code base and only a few dependencies on widely-used crates allow for easy code audits.
• Secure default settings, yielding passwords with an entropy of at least 256 bits.

Missing Features

This application is supposed to do one thing and do it well, so it is intentionally kept small.
Nevertheless, some features are currently missing.

Usage

Disclaimer

I personally use this app as my password generator, as I don't trust closed-source websites on generating passwords.

My main motivation with this repository is to have a best-practices template for Rust projects available as a reference for new projects. I will also use this repository as an integration test for better CI/CD on GitHub.

If you want to use this app for yourself, please check the source code in advance. I welcome any issue reports and pull requests on this GitHub repository.
