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.

Command — copy this

grep -E 'Scope|refusals|JWT' "$CRYPTO_LAB/report/crypto-report-template.md"
grep FINDING "$CRYPTO_LAB/report/finding-draft.txt"

═══ WINDOWS ═══

Command — copy this

Get-Content $HOME/cyberlium-lab/t28-crypto/report/crypto-report-template.md | Select-String refusals
Get-Content $HOME/cyberlium-lab/t28-crypto/report/finding-draft.txt | Select-String Scope

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.
