====== Razred CertificateRequestExtensions ======

Zagotavlja razširitvene metode za ''CertificateRequest'' s PQ-podporo.

----

===== Definicija =====

<code csharp>
namespace WvdS.System.Security.Cryptography.X509Certificates

public static class CertificateRequestExtensions
</code>

----

===== Metode =====

^  Ime  ^  Opis  ^
| CreateSelfSigned(DateTimeOffset, DateTimeOffset, CryptoMode?) | Ustvari samopodpisan certifikat z opcijskim PQ-podpisom |
| Create(X509Certificate2, DateTimeOffset, DateTimeOffset, Byte[], CryptoMode?) | Ustvari CA-podpisan certifikat z opcijskim PQ-podpisom |

----

===== Opombe =====

Ta razred razširitev razširja ''System.Security.Cryptography.X509Certificates.CertificateRequest''((Microsoft Docs: https://learn.microsoft.com/dotnet/api/system.security.cryptography.x509certificates.certificaterequest)).

==== Obnašanje Drop-In ====

Razširitvene metode imajo enako signaturo kot originalne metode plus opcijski parameter ''CryptoMode'':

<code csharp>
// Originalna .NET
X509Certificate2 CreateSelfSigned(DateTimeOffset notBefore, DateTimeOffset notAfter)

// Razširitev (Drop-In)
X509Certificate2 CreateSelfSigned(DateTimeOffset notBefore, DateTimeOffset notAfter, CryptoMode? mode = null)
</code>

Ko je imenski prostor ''using'' vključen, se samodejno uporabi razširitvena metoda.

----

===== Primer =====

<code csharp>
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));

// Hibridni certifikat: RSA + ML-DSA
var cert = request.CreateSelfSigned(
    DateTimeOffset.Now,
    DateTimeOffset.Now.AddYears(1));
</code>
