Any majority of shards can reconstruct the secret — fewer reveal nothing.\n\n<b>How it works</b>\n\n1. Enter your secret (e.g., a seed phrase, private key, password).\n2. Choose how many shards to create and how many are required to reconstruct.\n3. Use the auto-generated passphrase or enter your own.\n4. Banana Split encrypts the secret with the passphrase, then splits the ciphertext into N QR codes using Shamir's scheme.\n5. Print or save the QR codes. Write the passphrase by hand on every sheet.\n\nTo reconstruct: scan a majority of QR code shards, enter the passphrase, and your secret is restored.\n\n<b>Features</b>\n\n• Offline — all cryptography happens on-device, no server communication\n• Save shards as PNGs or PDF with full Unicode font support\n• Open saved shards in another app, save them to Downloads or any folder, or share them\n• Camera and gallery QR scanning with multi-file import\n• Custom or auto-generated passphrases\n• User-selectable quorum (how many shards needed)\n• 9 languages: English, Russian, Turkish, Belarusian, Georgian, Ukrainian, Polish, Spanish, Italian\n• Cross-platform shard compatibility with the Banana Split web app\n\n<b>Security</b>\n\nEncryption: scrypt key derivation + NaCl secretbox (XSalsa20-Poly1305).\nSplitting: Shamir's Secret Sharing over GF(256).\nNo data collection, no analytics, no trackers.\n\n<b>Web App</b>\n\nAlso available as a web app — no installation needed: https://nfcarchiver.com/banana/\nShards created in the app and web version are fully compatible.\n\n<b>Open Source</b>\n\nThis app is a fork of banana_split by Parity Technologies, licensed under GPLv3.\nSource code: https://github.com/mezinster/banana_split\n","categories":["System","Text Encryption"]}
