How Can I Resolve Python Requests SSLError: Untrusted SSL Certificate?

Addressing Python Requests SSLError: A Path to SSL Validation

Facing an SSLError when working with Python Requests can be a frustrating obstacle. This issue arises due to an untrusted SSL certificate. To understand where the SSL certificate is expected, let's delve into the problem's details.

Quick Fix: Disabling Certificate Verification

The most expedient solution is to set the verify parameter to False:

requests.get('https://example.com', verify=False)

However, this compromises security by bypassing certificate verification, potentially exposing your application to vulnerabilities.

Optimal Solution: Trusted SSL Certificate

A more secure approach is to obtain a trusted SSL certificate and set the verify parameter to its path as a string:

requests.get('https://example.com', verify='/path/to/cert.pem')

In Requests version 2.0 and above, the verify parameter provides flexibility:

• True: Validates the certificate against predefined trusted authorities.
• False: Disables certificate verification entirely.
• CA_BUNDLE File Path: Specifies a custom file containing trusted CA certificates.

To further enhance your understanding, explore the cert parameter in the Requests documentation: https://requests.readthedocs.io/en/master/user/advanced/#ssl-cert-verification
