rs-random

Secure String Generator

A minimal, blazing-fast Rust command-line tool for generating secure random strings with the tiniest possible footprint. Perfect for standalone use or integration into other applications.

Features

Uses operating system entropy (OsRng) for cryptographically secure randomness
Very small binary size (optimized release profile)
Minimal dependencies (only the rand crate with std_rng and getrandom features)
Flexible selection of character sets, including alphabets, numbers, symbols, and more

About

I created rs-random to have a super simple, minimal way to generate secure strings that I could build into other applications, ensuring security, speed, and a tiny footprint.
