Overview:

• The SSL module in Python provides functions and classes  to support TLS - Transport Layer Security(or the old and still interchangeably  used name SSL).

• The TLS specification defines requirements for secure communication between connection oriented sockets.

• The Python SSL module enables Python programs that use connection based sockets with the following
  • Privacy (Through Cryptography)
  • Integrity (Through Message Digests)
  • Authentication (Through Digital Certificates)

• To provide these services the Python SSL module relies on the OpenSSL library (pre)installed in the Operating System.
