PrePostQuantumSignatureAPI

A unified C# API framework for integrating pre-quantum and post-quantum digital signature schemes. The library provides a consistent, strongly typed abstraction for developers, supporting both classical algorithms such as RSA and ECDSA and post-quantum schemes including CRYSTALS-Dilithium, SPHINCS+, and Falcon.

Features

  • Unified, algorithm-neutral signature interface
  • Strongly typed public and private keys to prevent misuse
  • Runtime selection of signature algorithms
  • Safe memory handling and zeroization for private keys
  • Support for .NET 9.0 and native C based cryptographic implementations
  • Ships with required native DLLs for Windows

Installation

dotnet add package PrePostQuantumSignatureAPI

Quick Start

Generate Keys

using MasterThesis.Core;

var selector = new SignatureSchemeSelector();
var scheme = (ISignatureSchemeDynamic)selector.GetRawScheme("rsa");

var keys = scheme.GenerateKeysDynamic();

Console.WriteLine($"Public Key: {keys.PublicKey}");
Console.WriteLine($"Private Key: {keys.PrivateKey}");

Sign a Message

byte[] message = System.Text.Encoding.UTF8.GetBytes("Hello PQ World");
byte[] signature = scheme.SignDynamic(message, keys.PrivateKey);

Console.WriteLine($"Signature: {Convert.ToBase64String(signature)}");

Verify a Signature

bool isValid = scheme.VerifyDynamic(message, signature, keys.PublicKey);
Console.WriteLine($"Signature valid: {isValid}");

Supported Algorithms

  • RSA (15360-bit)
  • ECDSA (P-521)
  • EdDSA (Ed25519)
  • CRYSTALS-Dilithium (ML-DSA-87)
  • SPHINCS+ (SPHINCS+-SHAKE-256f)
  • Falcon (Falcon-1024)

Runtime Algorithm Selection

Runtime Selection is possible with the Additional WebAPI, which can be found on the Github page. With that, signature algorithms can be selected at runtime without code changes:

var scheme = (ISignatureSchemeDynamic)selector.GetRawScheme("dilithium");

This enables seamless switching between classical and post-quantum schemes using configuration or user input.

Native Dependencies

The package includes required native binaries under:

runtimes/win-x64/native

These are automatically resolved when running on Windows x64 systems.
