∟Communicating with HTTPS Servers

This chapter provides tutorial notes and example codes on writing Python scripts to communicate with HTTPS servers. Topics include using built-in http.client and ssl modules; modifying SSL parameters; retrieving server certificate and validation chain; installing and using the pyOpenSSL package.

http.client for HTTPS Connection

Modifying SSL Parameters

Retrieving SSLSocket Information

Dumping Server Certificate

Use pyOpenSSL for HTTPS Connection

Takeaways:

http.client is a built-in module that supports both HTTP and HTTPS protocols.
ssl is a built-in module that wraps the OpenSSL library to provide TLS/SSL services for the http.client module.
http.client uses an ssl.SSLContext object to control SSL connection parameters.
http.client.HTTPSConnection represents the HTTPS connection.
HTTPSConnection.sock can be used to retrieve remote server certificate.
OpenSSL.SSL module in the pyOpenSSL package can also be used to make HTTPS connection.
