CRYSTALS Kyber & Dilithium for Delphi / Pascal

This project provides a Delphi/Object Pascal port of the official CRYSTALS-Kyber and CRYSTALS-Dilithium reference implementations from the PQ-CRYSTALS C projects.

The code is designed to stay structurally close to the original C sources, making it easy to compare, test and validate against the official implementations.

The project can be used with Delphi and Free Pascal Compiler (FPC), including on Windows and Linux platforms.

Included Algorithms

CRYSTALS-Kyber

Kyber is a post-quantum key encapsulation mechanism.

Supported parameter sets:

• Kyber512
• Kyber768
• Kyber1024

Typical operations:

• Generate key pair
• Encapsulate shared secret
• Decapsulate shared secret

CRYSTALS-Dilithium

Dilithium is a post-quantum digital signature scheme.

Supported parameter sets:

• Dilithium2
• Dilithium3
• Dilithium5

Typical operations:

• Generate key pair
• Sign messages
• Verify signatures

uses
  kyber,
  dilithium,
  fips202;

Example usage is available in the included test projects.

Notes

This is a direct port of the official reference implementations and is intended for testing, research, interoperability checks and integration experiments.

Before using it in production or security-critical environments, additional review and validation are strongly recommended.
