What is cryptography-rs?

This repository is a collection of cryptography tools written in Rust. The crates here were created primarily to support other projects, particularly implementing code signing (a way to verify that software comes from a trusted source) entirely in the Rust programming language, rather than relying on existing tools from other languages. Think of these crates as building blocks. If you're writing a Rust application and need to do cryptographic operations, like encrypting data, verifying signatures, or hashing information, you could potentially use one of these tools instead of hunting for an external dependency. The repository bundles several related crates together so they can share development effort and be maintained in one place. The author is transparent about the limitations: they're not a cryptography expert, and these crates haven't all been thoroughly audited by security specialists. This means they're fine for learning, experimentation, or less critical applications, but you should be careful before using them in high-stakes security situations, like protecting passwords, financial data, or critical infrastructure. If you do use them, it's wise to have a security professional review the specific code paths you're relying on. The repository is open source and the author welcomes financial support through GitHub Sponsors or Patreon if you find the work valuable and want to help fund ongoing development and maintenance.
