我有以下代码生成一个很好的自签名证书,效果很好,但我想更新到最新的BouncyCastle(1.8.1.0),我收到有关过时使用的警告:

var persistedCertificateFilename = "ClientCertificate.pfx";
if (!string.IsNullOrWhiteSpace(ConfigurationManager.AppSettings["PersistedCertificateFilename"])) { persistedCertificateFilename = ConfigurationManager.AppSettings["PersistedCertificateFilename"].Trim(); }
if (persistCertificateToDisk)
{
    if (File.Exists(persistedCertificateFilename))
    {
        var certBytes = File.ReadAllBytes(persistedCertificateFilename);
                this.clientCertificate = new X509Certificate2(certBytes, (string) null, X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet);
    }
}

if (this.clientCertificate == null)
{
    // Initialize the new secure keys
    KeyGenerator keyGenerator = KeyGenerator.Create();
    KeyPair keyPair = keyGenerator.GenerateKeyPair();
    this.privateKey = keyPair.ToEncryptedPrivateKeyString(privateKeySecret);
    this.publicKey = keyPair.ToPublicKeyString();

    // Client certificate permissions
    var certificatePermissions = new ArrayList()
    {
         KeyPurposeID.IdKPCodeSigning,
         KeyPurposeID.IdKPServerAuth,
         KeyPurposeID.IdKPTimeStamping,
         KeyPurposeID.IdKPOcspSigning,
         KeyPurposeID.IdKPClientAuth
    };

    // Initialize the certificate …
