示例1: SafeFreeCertContext
public SafeFreeCertContext(SafeX509Handle certificate) : base(IntPtr.Zero, true)
{
// In certain scenarios (eg. server querying for a client cert), the
// input certificate may be invalid and this is OK
if ((null != certificate) && !certificate.IsInvalid)
{
bool gotRef = false;
certificate.DangerousAddRef(ref gotRef);
Debug.Assert(gotRef, "Unexpected failure in AddRef of certificate");
_certificate = certificate;
handle = _certificate.DangerousGetHandle();
}
}示例2: AllocateSslContext
internal static SafeSslHandle AllocateSslContext(SslProtocols protocols, SafeX509Handle certHandle, SafeEvpPKeyHandle certKeyHandle, EncryptionPolicy policy, bool isServer, bool remoteCertRequired)
{
SafeSslHandle context = null;

{
if (innerContext.IsInvalid)
{

}
// Configure allowed protocols. It's ok to use DangerousGetHandle here without AddRef/Release as we just
// create the handle, it's rooted by the using, no one else has a reference to it, etc.
Ssl.SetProtocolOptions(innerContext.DangerousGetHandle(), protocols);
// The logic in SafeSslHandle.Disconnect is simple because we are doing a quiet
// shutdown (we aren't negotiating for session close to enable later session
// restoration).
//
// If you find yourself wanting to remove this line to enable bidirectional
// close-notify, you'll probably need to rewrite SafeSslHandle.Disconnect().
// https://www.openssl.org/docs/manmaster/ssl/SSL_shutdown.html
