FoundKey is a hands-on cryptography toolkit and learning app. Run real cryptographic operations, see exactly how ciphers transform your text, build multi-step cipher recipes, and trade encrypted messages and code-cracking challenges with friends - all in a beautiful, fast, fully offline app. WORKBENCH - 45+ OPERATIONS • Encode & decode: Base64, Hex, Binary, URL, Morse code (with audio playback), and more • Classical ciphers: Caesar, Vigenère, Atbash, Rail Fence, Playfair, Enigma, and friends • Modern crypto: AES, ChaCha20, Blowfish, and other symmetric ciphers • Hashing & key derivation: SHA-256 and the SHA-2 family, MD5, BCrypt, Argon2 • Utilities: frequency analysis, text tools, random keys, and more SEE HOW CIPHERS ACTUALLY WORK Tap "Explain" and watch your own text get transformed step by step - letter shifts, key alignment, rail patterns. It's the fastest way to truly understand a cipher: not a diagram from a textbook, but your message, traced live. CIPHER LAB - BUILD YOUR OWN ENCRYPTION Chain operations into reusable recipes: Vigenère into Base64 into reversed text — whatever you can dream up. Save, color-tag, and share recipes, or publish them as "black box" puzzles where friends must figure out the password. LEARN - A CRYPTOGRAPHY LIBRARY IN YOUR POCKET Illustrated chapters take you from ancient ciphers to modern encryption and hashing, with progress tracking as you read, test, and master each topic. MESSAGES - REAL ENCRYPTED NOTES Compose messages encrypted with real algorithms and pass them to friends by QR code, AirDrop, or link. They decrypt in the recipient's app with the key you share. No accounts, no servers — the message travels inside the code itself. CHALLENGES - CRACK THE CODE Solve built-in puzzles across difficulty tiers, race the clock, use hints sparingly - or craft your own challenges and dare your friends. PRIVATE BY DESIGN • No account, no ads, no analytics, no tracking • Everything stays on your device; works fully offline • Sensitive clipboard copies expire automatically and never sync to other devices • History auto-deletes on your schedule POWER-USER FRIENDLY • Siri Shortcuts for Base64, Hex, and SHA-256 • Spotlight search for operations, articles, and recipes • Deep links and .cwb files for sharing • Beautiful native design for iPhone and iPad, light and dark FREE VS PREMIUM Free forever: all 45+ operations, 5 cipher recipes, the first Learn chapters, starter challenge packs, and unlimited message exchange.
