.NET 10 Post Quantum Cryptography, example with ML-KEM

Program.cs

using System; 
using System.Security.Cryptography; 

// 1) Server generates a KEM key pair 
using var serverKey = MLKEM.GenerateKey(MLKEMAlgorithm.MLKEM768); 

// Export public key 
string serverPublicPem = serverKey.ExportSubjectPublicKeyInfoPem(); 

// 2) Client imports public key 
using var clientKey = MLKEM.ImportFromPem(serverPublicPem); 

// Client encapsulates a shared secret 
(byte[] ciphertext, byte[] clientSharedSecret) = clientKey.Encapsulate(); 

// 3) Server decapsulates using private key 
byte[] serverSharedSecret = serverKey.Decapsulate(ciphertext); /

// 4) Both sides now share the same secret 
Console.WriteLine( Convert.ToBase64String(clientSharedSecret) == Convert.ToBase64String(serverSharedSecret) );
