NativeCryptoProvider

Prostor imena: WvdS.System.Security.Cryptography.Providers

P/Invoke-temeljeni kripto-provider za posluziteljske i desktop aplikacije. Komunicira izravno s OpenSSL 3.6 putem Platform Invocation Services.

NativeCryptoProvider je standardni provider za:

• Blazor Server
• ASP.NET Core
• Desktop aplikacije (Windows, Linux, macOS)
• Konzolne aplikacije
• Windows servise / Linux daemone

using WvdS.System.Security.Cryptography.Providers;
 
// Kreiranje providera
var provider = new NativeCryptoProvider();
 
// Inicijalizacija (ucitava OpenSSL)
await provider.InitializeAsync();
 
// Provjera dostupnosti
if (provider.IsAvailable)
{
    Console.WriteLine($"Provider: {provider.Name}");
    Console.WriteLine($"OpenSSL: {provider.GetOpenSslVersion()}");
}

Generira ML-DSA par kljuceva.

var (publicKey, privateKey) = await provider.GenerateMlDsaKeyPairAsync("ML-DSA-65");
 
// Podrzani algoritmi:
// - "ML-DSA-44" (NIST razina 1)
// - "ML-DSA-65" (NIST razina 3, preporuceno)
// - "ML-DSA-87" (NIST razina 5)

byte[] data = Encoding.UTF8.GetBytes("Vazni podaci");
byte[] signature = await provider.SignMlDsaAsync(data, privateKey);
bool isValid = await provider.VerifyMlDsaAsync(data, signature, publicKey);

var (publicKey, privateKey) = await provider.GenerateMlKemKeyPairAsync("ML-KEM-768");
 
// Podrzani algoritmi:
// - "ML-KEM-512" (NIST razina 1)
// - "ML-KEM-768" (NIST razina 3, preporuceno)
// - "ML-KEM-1024" (NIST razina 5)

var (sharedSecret, ciphertext) = await provider.EncapsulateAsync(recipientPublicKey);
byte[] sharedSecret = await provider.DecapsulateAsync(ciphertext, privateKey);

// Postavite putanju prije InitializeAsync()
CryptoConfig.OpenSslPath = @"C:\OpenSSL\bin";
 
var provider = new NativeCryptoProvider();
await provider.InitializeAsync();
