Fields

Default 240

Use None instead of Default. Default permits only the Secure Sockets Layer (SSL) 3.0 or Transport Layer Security (TLS) 1.0 protocols to be negotiated, and those options are now considered obsolete. Consequently, Default is not allowed in many organizations. Despite the name of this field, SslStream does not use it as a default except under special circumstances.

None 0

Allows the operating system to choose the best protocol to use, and to block protocols that are not secure. Unless your app has a specific reason not to, you should use this field.
