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• Camera and gallery QR scanning with multi-file import\n• Custom or auto-generated passphrases\n• User-selectable quorum (how many shards needed)\n• 7 languages: English, Russian, Turkish, Belarusian, Georgian, Ukrainian, Polish\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":["Security","System"]}
