At Codernix Solutions OÜ, we believe that open source is the engine of modern software innovation. It fosters collaboration, transparency, and community, allowing developers to build better software, faster. We are proud to contribute back to the community that has given us so much.
This page is a curated list of our open-source projects. Each one is born from a real-world need we encountered and is built with the same commitment to quality and performance that we apply to all our work.
We invite you to explore, use, and contribute to our projects.
Our Projects
Cryptographic Libraries & Tools
Security is not an afterthought; it’s a foundation. Our cryptographic contributions focus on providing developers with accessible, high-speed implementations of modern, secure algorithms.
Codernix BLAKE3 C Wrapper
A high-performance C shared library, built in Rust, that exposes the modern BLAKE3 hashing algorithm. It’s perfect for speeding up cryptographic operations in performance-sensitive environments like PHP extensions.
More details can be found here.
A high-performance PHP extension built directly on top of our C wrapper. This project brings the incredible speed of BLAKE3 into the PHP ecosystem, exposing it as a simple, native function: blake3_hash(). It’s the perfect solution for developers who need to perform intensive hashing for file integrity checks, data verification, or custom lookups without sacrificing performance.

Codernix ED25519 PHP Extension
A PHP extension for the Ed25519 digital signature system that delivers exceptional performance by leveraging a custom assembly implementation from the SUPERCOP crypto bundle. A significant part of this project involved adapting the original assembly code to be fully position-independent (PIC), a necessary step to create a stable and portable shared library for PHP. This provides a robust solution for high-throughput applications requiring fast signature verification.
