Post-Quantum Cryptography for the PHP Community
Summary
Paragon Initiative Enterprises announces two open source PHP projects to mitigate post-quantum cryptography risks in PHP applications: ext-pqcrypto, a Rust-based PHP extension wrapping RustCrypto post-quantum KEMs and signature algorithms, and pqcrypto_compat, a pure-PHP fallback. The post explains motivation, outlines integration approaches for PHP software, and emphasizes a cautious, iterative migration toward quantum-resistant crypto by 2029.
