FoundKey vs Dit

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.

Dit teaches Morse code by ear, not by eye. There's no need to memorize a dot-and-dash chart. You hear each character as a sound and tap it back. Characters play at real speed from the start. If they played slowly enough to count individual dots and dashes, you'd do exactly that, and then you'd be stuck translating forever instead of just hearing the letter. The spacing between letters starts generous and tightens as you improve. Choose how you practice: - Practice walks you through small groups of letters and advances when you're ready. - Freestyle lets you tap whatever you want and see what it decodes to. - Listen trains recognition of characters, common English words, and Q codes. You can also play your own text and optionally type along to check your copy. - Conversation lets you practice a simulated CW contact with an AI operator. Hear the other station, then key your reply, including continuous prosigns. Practice and Freestyle also support external Morse paddles through VBand-compatible adapters. For example, you can use a Bencher BY-1 iambic paddle with a compatible USB=C adapter. Connect your adapter to your iPhone or iPad, open Practice or Freestyle, and use the left paddle for dits and the right for dahs. Letter practice notices which characters trip you up and brings them back more often. Review Misses drills your weak spots. Dit tracks how quickly you recognize each character, so you can tell where you're sharp versus where you're still guessing. Letters are introduced in small packs that let you build common words and radio abbreviations. Track your progress in the app and with Home Screen or Lock Screen widgets. Core practice works offline. Progress saves on your device. Sign in to sync across devices if you want, but you don't have to. Conversation mode requires an internet connection. Before each contact, you choose whether to send your keyed messages and conversation history to Google Gemini to generate replies. Typed reception copy stays on your device.
