Python Requests TLS

As someone who has worked with Python Requests library, I have had to deal with TLS connections while making HTTP requests.

What is TLS?

Transport Layer Security (TLS) is a protocol that provides privacy and data integrity between applications communicating over a network. It is the successor to SSL (Secure Sockets Layer) protocol.

How to use TLS with Python Requests?

Python Requests library provides an easy-to-use interface for making HTTP requests. By default, it uses the system's default SSL library to establish secure connections. However, you can also specify the version of TLS to use.


import requests

# Make a request using TLS v1.2
response = requests.get('https://example.com', verify=True, headers={'Connection': 'close'}, timeout=5.0, allow_redirects=True, stream=True, cert=None, proxies=None)

# Make a request using TLS v1.3
response = requests.get('https://example.com', verify=True, headers={'Connection': 'close'}, timeout=5.0, allow_redirects=True, stream=True, cert=None, proxies=None, tls_version= requests.adapters.DEFAULT_TLS_VERSION)

The above code snippets show how to make a request using TLS v1.2 and v1.3 respectively. The 'verify' parameter tells Requests to verify the SSL certificate. 'headers' parameter specifies the HTTP headers to be sent with the request. 'timeout' parameter sets the timeout for the request. 'allow_redirects' parameter specifies whether to follow redirects or not. 'stream' parameter specifies whether to receive the response in chunks. 'cert' parameter specifies the client-side SSL certificate to use. 'proxies' parameter specifies the proxy server to be used.

The 'tls_version' parameter specifies the version of TLS to use. You can set it to 'requests.adapters.DEFAULT_TLS_VERSION' to use the default version of TLS.

Conclusion

Using Python Requests library, you can easily make HTTP requests using TLS connections. You can specify the version of TLS to use and other parameters to customize your requests.
