Does Python Requests use TLS 1.3?

If you are working with web applications or websites, you may know that the data being transmitted over the internet can be intercepted and read by malicious actors. That's why secure communication protocols, like TLS, are used to encrypt the data between a client and a server.

Python Requests is a popular library used for making HTTP requests in Python. It supports different versions of TLS, including TLS 1.3. In fact, Python Requests uses the underlying SSL library provided by Python, which also supports TLS 1.3.

To use TLS 1.3 with Python Requests, you need to ensure that the server you are connecting to also supports TLS 1.3. You can do this by sending a TLS version negotiation request during the handshake process.

Using Python Requests with TLS 1.3

Here is an example of making an HTTPS request using Python Requests with TLS 1.3:


    import requests

    # Set the URL to the website you want to access
    url = 'https://example.com'

    # Send the request with TLS 1.3
    response = requests.get(url, verify=True, tls_version='TLSv1.3')

    # Print the contents of the response
    print(response.content)

In the above code, we are using the requests.get() method to send an HTTPS GET request to the URL 'https://example.com'. We have set the verify parameter to True, which means that Python Requests will verify the SSL certificate presented by the server. We have also set the tls_version parameter to 'TLSv1.3', which tells Python Requests to use TLS 1.3 for the connection.

Other ways to use TLS 1.3 with Python

Python Requests is not the only way to use TLS 1.3 in Python. You can also use the built-in http.client module, which provides a lower-level interface for making HTTP requests. Here is an example:


    import http.client

    # Set the URL to the website you want to access
    url = 'example.com'

    # Open a connection with TLS 1.3
    conn = http.client.HTTPSConnection(url, tls_version='TLSv1.3')

    # Send a GET request
    conn.request("GET", "/")

    # Get the response
    response = conn.getresponse()

    # Print the contents of the response
    print(response.read())

In the above code, we are using the http.client.HTTPSConnection() method to open a connection with the server using TLS 1.3. We then send a GET request using the conn.request() method and get the response using the conn.getresponse() method. Finally, we print the contents of the response.
