WvdS.System.Security.Cryptography

WvdS Crypto Library

WvdS.System.Security.Cryptography

Post-quantum cryptography extension for .NET - based on OpenSSL 3.6.

Overview

WvdS.System.Security.Cryptography extends System.Security.Cryptography¹⁾ from Microsoft with post-quantum cryptography. The library uses OpenSSL 3.6²⁾ for ML-DSA³⁾ and ML-KEM⁴⁾ algorithms.

Platforms: .NET 8.0+, Blazor Server, Blazor WebAssembly

Quick Start

dotnet add package EMSR.Crypto

using WvdS.System.Security.Cryptography;
 
CryptoConfig.DefaultMode = CryptoMode.Hybrid;
 
// Existing code automatically works with PQ
var cert = request.CreateSelfSigned(notBefore, notAfter);
