Winsock 2.0
Advantages	Disadvantages
Implements SSL/PCT securely outside of the application. Access to Internet and other application protocols such as telnet. High degree of flexibility.	Need to embed knowledge of TCP/IP and Windows sockets. Need to embed knowledge of Internet protocols. More complex.
WinInet API 2.0
Advantages	Disadvantages
Using SSL is as simple as setting a flag. Eliminates the need to embed knowledge of TCP/IP and Windows sockets. Eliminates the need to embed knowledge of Internet protocols. 4 Provides a constant interface to the evolving underlying protocols. Follows Win32 function standards. Fast implementation.	Does not support application protocols such as telnet. Not as flexible.
