Classe CertificateRequestExtensions

Fornisce Extension Methods per CertificateRequest con supporto PQ.

namespace WvdS.System.Security.Cryptography.X509Certificates
 
public static class CertificateRequestExtensions

Questa classe extension estende System.Security.Cryptography.X509Certificates.CertificateRequest¹⁾.

Gli Extension Methods hanno la stessa firma dei metodi originali piu un parametro CryptoMode opzionale:

// Originale .NET
X509Certificate2 CreateSelfSigned(DateTimeOffset notBefore, DateTimeOffset notAfter)
 
// Extension (Drop-In)
X509Certificate2 CreateSelfSigned(DateTimeOffset notBefore, DateTimeOffset notAfter, CryptoMode? mode = null)

Se il namespace using e incluso, viene utilizzato automaticamente l'Extension Method.

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=Server, O=Org, C=DE",
    rsa,
    HashAlgorithmName.SHA256,
    RSASignaturePadding.Pkcs1);
 
request.CertificateExtensions.Add(
    new X509BasicConstraintsExtension(false, false, 0, true));
 
// Certificato ibrido: RSA + ML-DSA
var cert = request.CreateSelfSigned(
    DateTimeOffset.Now,
    DateTimeOffset.Now.AddYears(1));
