What this task asks for
Create a 2048-bit RSA key and one-year self-signed certificate for the specified internal host, plus combined and human-readable verification artifacts. Generate a 2048-bit RSA key with mode 600. Set organization DevOps Team and common name dev-internal.company.local. Make the certificate valid for 365 days. Record subject, validity dates, and SHA-256 fingerprint. Print the common name, expiration date, and success message from check_cert.py.
