About:
Certifi is a curated collection of Root Certificates for validating the trustworthiness of SSL/TLS certificates in Python applications. It provides the 'certifi.cacert.pem' file, enabling secure HTTPS connections by default. This package ensures Python can verify certificates from trusted Certificate Authorities.

Key Features:

Provides a comprehensive, up-to-date bundle of trusted CA root certificates
Enables SSL/TLS verification for Python's standard library and requests
Decoupled from Python's release cycle for faster security updates
Simple API to access the path of the CA bundle

Use Cases:

Verifying SSL/TLS certificates when making HTTPS requests with the 'requests' library
Securing outgoing API calls from Python applications
Ensuring consistent certificate validation across different environments

Alternatives:

system-provided CA store – System stores offer OS-level integration but may be outdated or inconsistent across platforms; certifi provides a portable, consistent bundle.
