Original Description

Starting in MongoDB 4.0, we now use the native crypto libraries available on the OS:

• Linux and *BSD: OpenSSL 
• Windows: SecureChannel 
• macOS X: SecureTransport

There also appear to be a number of places in the 4.0 manual where we call out OpenSSL specifically as the transport security implementation MongoDB uses–these should also be adjusted slightly for accuracy. I can move this part to a dedicated ticket if preferred.
