Crackmes.one RE CTF 2026

Static site for the 1st Crackmes.one Reverse Engineering CTF.

Live site: https://ctf.crackmes.one

Switching Between Versions

The site has two modes controlled by config.js:

Mode	isEventOver	Shows
Live	false	"CTF is LIVE!" banner + Enter CTF button
Ended	true	"CTF has ended!" banner + Hall of Fame

Switch to "CTF Ended" mode

# 1. Download scoreboard CSV from CTFd admin panel
#    (Admin -> Scoreboard -> Export CSV)

# 2. Convert CSV to JSON (strips emails, keeps rank/name/score only)
python3 convert-scoreboard.py "Crackmesone CTF-scoreboard.csv"

# 3. Flip the switch
sed -i '' 's/isEventOver: false/isEventOver: true/' config.js

# 4. Deploy
git add .
git commit -m "CTF ended - final scoreboard"
git push

Switch back to "Live" mode

sed -i '' 's/isEventOver: true/isEventOver: false/' config.js
git add config.js
git commit -m "Switch to live mode"
git push

Files

File	Purpose
config.js	Toggle isEventOver to switch modes
scoreboard.json	Player rankings (generated from CSV)
convert-scoreboard.py	Convert CTFd CSV export to JSON
index.html	Main page
style.css	Styling (matches crackmes.one theme)

Scoreboard

The Hall of Fame shows top 100 players by default with a "Show All Players" button to display everyone.

Converting from CTFd Export

1. Go to CTFd Admin -> Scoreboard -> Export (CSV)
2. Run: python3 convert-scoreboard.py "your-export.csv"
3. This creates scoreboard.json with only rank, name, and score (no emails)

JSON Format

{
  "standings": [
    {"rank": 1, "name": "player1", "score": 1000},
    {"rank": 2, "name": "player2", "score": 950}
  ]
}

Privacy

• .gitignore excludes *.csv files to prevent committing emails
• Only scoreboard.json (rank, name, score) is committed
