SSL Certificate error while doing a request via python

When making HTTP requests in Python using libraries like requests, you may encounter SSL certificate errors. These errors occur when the server's SSL certificate cannot be verified, possibly due to issues such as an expired certificate, a self-signed certificate, or a certificate from an untrusted certificate authority. This tutorial will guide you through understanding SSL certificate errors and how to handle them in your Python code.
Before we begin, make sure you have the requests library installed. You can install it using the following command:
SSL (Secure Sockets Layer) is a protocol for securing communication over a computer network. SSL certificates are used to establish a secure connection between a client and a server. When making an HTTPS request in Python, the requests library verifies the server's SSL certificate. If there's an issue with the certificate, an SSLError is raised.
Common SSL certificate errors include:
To handle SSL certificate errors in Python, you can use the verify parameter of the requests library. By default, verify is set to True, which means the library will verify SSL certificates. You can set it to False to disable certificate verification, but this is not recommended for security reasons.
A better approach is to provide a custom CA bundle that includes trusted certificates. You can use the cert parameter to specify the path to a CA bundle file.
Here's an example of how to handle SSL certificate errors using the requests library:
In this example, we attempt to make an HTTPS request to "https://example.com." If there's an SSL certificate error, it will be caught as an SSLError, and you can handle it accordingly.
To use a custom CA bundle, you can download a bundle file containing trusted certificates (e.g., from https://curl.se/ca/cacert.pem) and specify its path in the cert parameter:
This way, you have more control over the certificates used for verification.
Handling SSL certificate errors is crucial for secure communication in your Python applications. By understanding common SSL issues and using the requests library's verify and cert parameters, you can ensure secure and reliable communication with HTTPS servers. Remember to always prioritize security when dealing with SSL certificates in your applications.
