===== Beispiel =====

<code csharp>
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
using WvdS.System.Security.Cryptography;
using WvdS.System.Security.Cryptography.X509Certificates;

CryptoConfig.DefaultMode = CryptoMode.Hybrid;

using var rsa = RSA.Create(2048);
var request = new CertificateRequest("CN=Test", rsa,
    HashAlgorithmName.SHA256, RSASignaturePadding.Pkcs1);

// Extension-Method wird automatisch verwendet
var cert = request.CreateSelfSigned(
    DateTimeOffset.Now,
    DateTimeOffset.Now.AddYears(1));

// PQ-Status prüfen
bool hasPq = cert.HasPqSignature();  // true
