How to use Requests with HTTPS URLs and SSL/TLS certificates

Digital certificates known as Secure Sockets Layer (SSL)certificates enable secure internet communication. A web server and a web browser establish a secure encrypted connection. When people go to a website, their browser starts a safe connection with the server. The browser and server check each other's identities during SSL/TLS handshakes.  

The SSL certificates encrypt the data exchange between the server and the browser. The encryption ensures that sensitive information remains confidential and secured from illegal access. Python SSL certificates also provide authentication and verification mechanisms. A Certificate Authority (CA) issues the certificate through a certificate issue procedure. SSL certificates enable trust chain indicators in web browsers. These indicators reassure site visitors that the connection is secure. There are several types of SSL certificates available.  

Here are some of the common types:  

• Single Domain Certificates   
• Wildcard Certificates   
• Multi-Domain (SAN) Certificates   
• Extended Validation (EV) Certificates   
• Organization Validated (OV) Certificates 

Setting up an SSL certificate file involves steps; here's an overview of the process:   

• Choose a trusted CA Certificate Authority or SSL Certificate Provider   
• Select the Type of SSL Certificate   
• Generate a Certificate Signing Request (CSR)   
• Submit CSR and Required Documents   
• Complete the Validation Process   
• Receive and install the SSL Certificate   
• Configure Your Web Server   
• Test and Verify SSL Configuration   
• Check and Maintain SSL Certificate  

Here are some tips to help you make an informed decision like   

• Determine Your Requirements,   
• Check the Validation Level   
• Consider Certificate Types and more.

FAQ

1. How does one set up a Python HTTPS server?   

To set up a Python HTTPS server, you can use the built-in http.server module in Python. But the http.server module only supports HTTP by default. You need to generate or get an SSL/TLS certificate and key pair to enable HTTPS.   

Here are the steps to set up a Python HTTPS server:   

• Generate or get an SSL/TLS certificate and key pair. To create a self-signed certificate for testing, you have two options. You can use tools like OpenSSL. Or you can buy a certificate from a certificate authority (CA) for production. Save the certificate to a secure location accessible by your Python script. Let's assume you have the following files:   

                                Certificate file: server.crt Key file: server.key   

• Write a Python script to set up the HTTPS server.   
• Save the script with a .py extension, such as https_server.py.   
• Open a terminal, navigate to the directory, and run it using the Python interpreter.   

2. Are earlier Python versions compatible with SSL certificates?   

Yes, earlier versions of Python are compatible with SSL certificates. All versions of Python have SSL/TLS capabilities and support SSL certificates. The Python standard library includes these features. Python 2.7 and Python 3.x versions provide SSL/TLS support through the SSL module. With this module, you can create safe connections and adjust SSL/TLS settings.  

Here's a general outline of how to use SSL certificates with Python:   

• Get an SSL certificate and key pair from a trusted CA or make a self-signed certificate for testing.   
• Save the certificate and key files to a secure location accessible by your Python script.   
• Use the SSL module in your Python script to configure SSL/TLS   
• Make the necessary modifications to your code to establish a secure connection.  

3. What is the Secure Sockets Layer, and how does it help secure internet traffic?   

The Secure Sockets Layer (SSL) is a cryptographic protocol. Used to provide secure communication over the Internet. It ensures the authenticity of data transmitted between a client and a server. Here's a breakdown of how SSL helps secure internet traffic:   

• Encryption  
• Data Integrity  
• Authentication  

4. How do you create a self-signed SSL certificate for Python applications?   

You can make an SSL certificate with OpenSSL, a free encryption library. Here are the steps to create a self-signed SSL certificate:   

• Install OpenSSL  
• Generate a Private Key   
• Generate a Certificate Signing Request (CSR)   
• Generate the Self-Signed Certificate   
• Copy the Certificate and Key Files   

5. Why do we use trusted CA certificates to verify secure connections?   

Trusted CA certificates are digital certificates issued by trusted Certificate Authorities (CAs). The communicating parties use them to verify secure connections. If a client connects to a server using SSL/TLS, the server shows its digital certificate.

Here's how we use trusted CA certificates to verify secure connections: 

• Certificate Issuance   
• Trust Chain   
• Certificate Verification   
• Chain of Trust
