Esempi compatti per Import/Export. → Dettagli: Scenari Import/Export

var cert = new X509Certificate2("certificate.pfx", "password");
 
// Certificato come PEM
string certPem = cert.ExportCertificatePem();
File.WriteAllText("certificate.pem", certPem);
 
// Chiave privata come PEM (cifrata)
using var key = cert.GetECDsaPrivateKey();
string keyPem = key.ExportEncryptedPkcs8PrivateKeyPem(
    "password"u8, new PbeParameters(
        PbeEncryptionAlgorithm.Aes256Cbc,
        HashAlgorithmName.SHA256, 100000));
File.WriteAllText("private.key", keyPem);

// Export
var cert = new X509Certificate2("certificate.pfx", "vecchia");
byte[] pfx = cert.Export(X509ContentType.Pfx, "nuova");
File.WriteAllBytes("exported.pfx", pfx);
 
// Import
var imported = new X509Certificate2("exported.pfx", "nuova",
    X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet);

→ Dettagli: Export PFX

// Export
var chain = new X509Certificate2Collection();
chain.Add(endEntity);
chain.Add(intermediate);
chain.Add(root);
 
byte[] p7b = chain.Export(X509ContentType.Pkcs7);
File.WriteAllBytes("chain.p7b", p7b);
 
// Import
var imported = new X509Certificate2Collection();
imported.Import("chain.p7b");

→ Dettagli: Catena PKCS#7

// Per Java: PKCS#12 con algoritmi compatibili
byte[] pfx = cert.Export(X509ContentType.Pfx, "password");
 
// Per OpenSSL: Formato PEM
string pem = cert.ExportCertificatePem();

# OpenSSL: PEM → PKCS#12
openssl pkcs12 -export -in cert.pem -inkey key.pem -out cert.pfx
 
# OpenSSL: PKCS#12 → PEM
openssl pkcs12 -in cert.pfx -out cert.pem -nodes
