Open Termux in the Academy folder and create the safe workspace. The companion generates samples, notes, and evidence files under your account.
python Smartphone-Academy.py prepare tls-certificate-auditNo root. Work only with the supplied files under $HOME.Practical mission
- Parse the supplied certificate details and identify subject, issuer, SAN entries, and validity dates
- Calculate the remaining validity period and flag an intentionally expired sample
- Explain the difference between encryption, hostname validation, and trust-chain validation
- Optionally compare the sample with a domain you own and document the exact command used
A tls-review.md that separates observed certificate facts, validation results, risks, and limitations.

Analyst reflection
Which result from “Optionally compare the sample with a domain you own and document the exact command used” needs additional evidence before it could support a real operational decision?
After checking the deliverables, run python Smartphone-Academy.py complete tls-certificate-audit. Progress is stored locally in the Termux home directory.
