Formato firma ibrida

In modalita Hybrid vengono generate due firme: 

+---------------------------------------------+
| Firma ibrida                                |
+---------------------------------------------+
| [4 Bytes] Lunghezza firma classica          |
| [n Bytes] Firma classica (RSA/ECDSA)        |
| [m Bytes] Firma PQ (ML-DSA)                 |
+---------------------------------------------+

Esempio

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("Dati da firmare");
 
// Creare firma ibrida
byte[] signature = rsa.SignData(
    data,
    HashAlgorithmName.SHA256,
    RSASignaturePadding.Pkcs1);
 
// Verificare
bool valid = rsa.VerifyData(
    data,
    signature,
    HashAlgorithmName.SHA256,
    RSASignaturePadding.Pkcs1);
