Lab — Setup
Pack crypto scope, toy inventory, and ethics card — lab setup file only, dest $CRYPTO_LAB.
Visual · t28_lab_setup
Lab: write crypto setup pack. $CRYPTO_LAB only. Original Cyberlium.
Opening
Lab setup before openssl or CTF solvers — scope paperwork crypto mentors expect.
Lessons 1–3 defined why advanced crypto matters, lab toys only, and production-oracle refusal. This lab ships the combined artifact: topic scope paragraph, toy inventory row, and ethics card for $CRYPTO_LAB. No exploit execution required — scope and toy paperwork first. Next: Quiz — Crypto Mindset and Lab.
1. Lab contract: write the setup pack
Create $HOME/cyberlium-lab/t28-m01-l04-lab-setup.txt with date, operator, $CRYPTO_LAB toy placeholder, literacy vs unauthorized probing paragraph, toy inventory row, and ethics card.
Optional: one-line proof your openssl or CTF toy folder exists — still no production oracle work required in this lab.

═══ INSTALL ═══
Linux (Debian/Ubuntu):
Command — copy this
sudo apt install curl
macOS: Built-in
Windows: Built-in (PowerShell: Invoke-WebRequest)
═══ LINUX / macOS ═══
Command — copy this
export CRYPTO_LAB=${CRYPTO_LAB:-$HOME/cyberlium-lab/t28-crypto}
cat > "$CRYPTO_LAB/roe.txt" <<'EOF'
CRYPTO_LAB=$HOME/cyberlium-lab/t28-crypto
targets: YOUR demo files, TOY RSA keys, self-signed lab certs only
never: padding-oracle on live sites, factor production RSA, JWT alg=none on stranger APIs
allowed: openssl enc/dgst/rand/genrsa/req/x509/s_client, python3 Caesar/XOR/freq, curl docs
private keys: chmod 600, never publish, never commit to git
EOFCommand — copy this
chmod 600 "$CRYPTO_LAB/roe.txt" grep -E 'CRYPTO_LAB|never|allowed|private keys' "$CRYPTO_LAB/roe.txt" command -v openssl >/dev/null && openssl version || echo 'openssl not installed — install for lab crypto literacy'
═══ WINDOWS ═══
Run on YOUR lab Windows VM only
Command — copy this
Get-Content $HOME/cyberlium-lab/t28-crypto/roe.txt | Select-String never
openssl version 2>$null; if (-not $?) { Write-Output 'Install OpenSSL for lab crypto literacy' }Primary tools to practice this lesson: grep, curl. Reference sites: RoE literacy (https://csrc.nist.gov/projects/cryptographic-standards-and-guidelines); OpenSSL man (https://www.openssl.org/docs/manmaster/man1/openssl.html); CWE (https://cwe.mitre.org/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Cross-check against misuse patterns
Grep notes for 'padding oracle script,' production API hostnames, live key dumps, or victim ciphertext — redact or delete. Rewrite forum habits to $CRYPTO_LAB placeholders before you copy workflows.
Classmates build their own setup packs for their $CRYPTO_LAB — not yours.
3. Lock the proof
chmod 600 on the pack. Quiz is next — then Primitives Literacy.
Crypto mentors archive lab setup before first openssl demo; you are practicing that habit early.
4. What you ship: crypto lab setup pack for $CRYPTO_LAB
Setup pack: scope, toy row, ethics card. $CRYPTO_LAB named. NEVER production oracles. chmod 600.
5. What you record before the next lesson
Date. Setup pack path. $CRYPTO_LAB scope note. File t28-m01-l04-lab-setup.txt chmod 600.
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
Skip the file and run oracle script on unknown API. Add production endpoint to approved list.
Right
Write YOUR lab setup pack for $CRYPTO_LAB. chmod 600. Next: Quiz — Crypto Mindset and Lab.
Mission: freeze YOUR lab setup pack on disk
1) Merge scope, toy, ethics sections. 2) Name $CRYPTO_LAB. 3) chmod 600. Never list production oracle analysis as approved practice.

Setup packs are boring on purpose — boring keeps crypto work defensible.
