.NET 10 Post Quantum Cryptography, example with SLH-DSA

Program.cs

using System; 
using System.Security.Cryptography; 

byte[] data = "critical firmware update"u8.ToArray(); 

// Generate SLH-DSA key 
using var signingKey = SLHDSA.GenerateKey(SLHDSAAlgorithm.SLHDSA128S);

// Sign the data 
byte[] signature = signingKey.SignData(data); 

// Export public key 
string publicPem = signingKey.ExportSubjectPublicKeyInfoPem(); 

// Import for verification 
using var verifyKey = SLHDSA.ImportFromPem(publicPem); 

// Verify signature 
bool ok = verifyKey.VerifyData(data, signature); 
Console.WriteLine(ok);
