CyberChef

A web app for encryption, encoding, compression, and data analysis — the "Cyber Swiss Army Knife" by GCHQ. All processing happens in the browser, no data is sent to the server.

What You Can Do After Deployment

1. Visit your domain — CyberChef loads instantly, ready to use
2. Drag & drop operations — pick from 300+ operations on the left panel
3. Build recipes — chain multiple operations together (e.g., Base64 Decode → Gunzip → JSON Beautify)
4. Save & share recipes — export your operation chains as URLs or JSON

Popular Operations

• Encoding/Decoding — Base64, URL, HTML Entity, Hex, Binary, Punycode
• Encryption/Decryption — AES, DES, Triple DES, Blowfish, RC4, RSA
• Hashing — MD5, SHA-1, SHA-256, SHA-512, HMAC, bcrypt
• Data Format — JSON, XML, YAML beautify/minify, CSV, Hex dump
• Networking — Parse IP ranges, decode URLs, extract domains, parse TLS
• Language — Text encoding (UTF-8, ASCII, Unicode), character codes
• Compression — Gzip, Bzip2, Zlib, Zip, Tar
• Regular Expressions — match, extract, replace with regex
• Visual — Render images, play audio, entropy graphs, hex viewer

Architecture

Single container, no database. All processing runs client-side in the browser.
