Format hibridnog potpisa

U hibridnom načinu rada generiraju se dva potpisa:

+---------------------------------------------+
| Hibridni potpis                             |
+---------------------------------------------+
| [4 bajta] Duljina klasičnog potpisa         |
| [n bajtova] Klasični potpis (RSA/ECDSA)     |
| [m bajtova] PQ potpis (ML-DSA)              |
+---------------------------------------------+

Primjer

using WvdS.System.Security.Cryptography;
using WvdS.System.Security.Cryptography.Signatures;
 
CryptoConfig.DefaultMode = CryptoMode.Hybrid;
 
using var rsa = RSA.Create(2048);
byte[] data = Encoding.UTF8.GetBytes("Podaci za potpisivanje");
 
// Kreiranje hibridnog potpisa
byte[] signature = rsa.SignData(
    data,
    HashAlgorithmName.SHA256,
    RSASignaturePadding.Pkcs1);
 
// Verifikacija
bool valid = rsa.VerifyData(
    data,
    signature,
    HashAlgorithmName.SHA256,
    RSASignaturePadding.Pkcs1);
