Revert a TLS Connection to Plain TCP

See more Socket/SSL/TLS Examples

Demonstrates Socket.ConvertFromSsl, which ends the TLS layer while leaving the underlying TCP connection open for subsequent unencrypted communication.

//  Connect to the server using TLS.

if (success = False) then
  begin
    Memo1.Lines.Add(CkSocket__lastErrorText(socket));

//  End the TLS layer while keeping the underlying TCP connection open for subsequent unencrypted
//  communication.  This is the reverse of a STARTTLS-style upgrade and is valid only while TLS is
//  active.
