Implementing Post-Quantum Cryptography in Go with crystals-go

The rapid advancement of quantum computing has spurred a critical need for cryptographic systems that can withstand attacks from quantum computers. Algorithms like RSA and ECC, which are widely used today, are vulnerable to quantum attacks. Enter post-quantum cryptography (PQC)—the next generation of cryptographic algorithms designed to secure data against both classical and quantum threats.

In this blog post, we’ll explore how to implement PQC in Go using the github.com/kudelskisecurity/crystals-go library, a Go-native implementation of the CRYSTALS-Kyber and CRYSTALS-Dilithium algorithms.
