Lab — Report
Crypto report lab on $CRYPTO_LAB — findings, libraries-not-DIY fixes, disclosure block; professional handoff pack.
Visual · t28_report_lab
Lab: crypto report pack from YOUR $CRYPTO_LAB work. Original Cyberlium.
Opening
Ship a mentor-ready crypto report — findings evidenced, library fixes cited, disclosure ethics signed — zero prod attack steps.
From $CRYPTO_LAB labs Modules 5–8: (1) report cover — scope, RoE reference, analyst, UTC; (2) ≥3 crypto finding drafts with libraries-not-DIY fix each; (3) responsible disclosure block — five MUST, five NEVER; (4) PKI/TLS hygiene summary from Modules 6–7; (5) limitations paragraph (toy vs prod, brief gaps); (6) integrity — $CRYPTO_LAB only, no prod oracles, no DIY crypto fixes, no key dumps; (7) chmod 600 index.md. Share-safe redaction optional per brief.
1. Report pack
Findings + library fixes + disclosure + PKI/TLS summary — cross-link prior labs.
Professional tone — ticket-ready titles.

Primary tools to practice this lesson: grep, python3. Reference sites: CWE (https://cwe.mitre.org/); NIST SP 800-57 (https://csrc.nist.gov/publications/detail/sp/800-57-part-1/rev-5/final); OpenSSL (https://www.openssl.org/docs/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Quality bar
Every finding cites observed artifact; fixes name library API not custom cipher.
Zero prod attack repro steps in any row.
3. Integrity scan
Scan for oracle cookbooks, key dumps, MITM steps — zero hits.
Practice label if brief requires.
4. What you ship: crypto report lab pack
Findings + library fixes + disclosure + integrity — chmod 600.
5. What you record before the next lesson

6. Wrong vs right: prod crypto oracles vs CTF toys
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Report lab includes prod padding-oracle walkthrough and key dump appendix.
Right
Crypto report lab pack on $CRYPTO_LAB. Next: quiz.
Mission: report lab
1) Three finding drafts with library fixes. 2) Disclosure MUST/NEVER block. 3) Limitations paragraph. 4) Integrity scan; chmod 600.
