How Can I Handle SSLError in Python Requests When Dealing with SSL Certificates?

Python Requests: Understanding SSLError

Python Requests, a popular HTTP library, commonly encounters SSLError when dealing with SSL-required authentications. This error stems from an untrusted SSL certificate.

Quick Fix: Disable Certificate Verification

To swiftly address this issue, one can set verify=False in the Requests call:

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

However, this approach comes with security risks (e.g., man-in-the-middle attacks) as it bypasses certificate validation.

Verify with Certificate Path

If bypassing certificate verification is impractical, a better solution is to provide the path to the .pem file containing the trusted certificate:

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

Requests Certificate Verification Options

As of version 2.0, Requests provides three options for handling SSL certification verification:

• True: Validates against the library's trusted certificates.
• False: Bypasses certificate validation.
• Path to a CA_BUNDLE file: Uses the specified file for certificate validation.

Refer to the Requests documentation on SSL Cert Verification for more detailed information, including options for customizing the verification process further. Additionally, the cert parameter can be used to specify the path to the actual certificate to validate against.
