Esempio

Nell'esempio di codice seguente viene inizializzato un RSACryptoServiceProvider oggetto per il valore di una chiave pubblica (inviata da un'altra parte), genera una chiave di sessione usando l'algoritmo Aes e quindi crittografa la chiave di sessione usando l'oggetto RSACryptoServiceProvider . Usando questo schema, la chiave di sessione potrebbe essere inviata al proprietario della chiave RSA privata e le due parti potrebbero usare la chiave di sessione per scambiare dati crittografati.
