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 is used automatically
var cert = request.CreateSelfSigned(
    DateTimeOffset.Now,
    DateTimeOffset.Now.AddYears(1));
 
// Check PQ status
bool hasPq = cert.HasPqSignature();  // true
