Securing Client Identity With Post-Quantum Cryptography
OpenSource For U, Tuesday, January 6th, 2026
Here's a quick tutorial on how to build a secure, real world client-server model that establishes client identity by using CRYSTALS-Dilithium, a post-quantum cryptography algorithm.
Encryption relies on mathematics to safeguard sensitive electronic information, such as websites and emails. Public-key encryption systems, which are widely used today, depend on mathematical problems that are computationally intractable, ensuring that websites and messages remain inaccessible to unauthorised third parties.
When developing new standards, NIST (National Institute of Standards and Technology) in the US evaluates not only the security of the algorithms' underlying the mathematics but also their most effective applications. The latest standards are designed to address two essential cryptographic tasks:
