Banana Split পাসওয়ার্ড ম্যানেজার অ্যাপ জন্য Android বর্ণনা
Banana Split uses Shamirs Secret Sharing to split secrets into QR-code shards. Any majority of shards can reconstruct the secret — fewer reveal nothing.
How it works
- Enter your secret (e.g., a seed phrase, private key, password).
- Choose how many shards to create and how many are required to reconstruct.
- Use the auto-generated passphrase or enter your own.
- Banana Split encrypts the secret with the passphrase, then splits the ciphertext into N QR codes using Shamirs scheme.
- Print or save the QR codes. Write the passphrase by hand on every sheet.
To reconstruct: scan a majority of QR code shards, enter the passphrase, and your secret is restored.
Features
- Offline — all cryptography happens on-device, no server communication
- Save shards as PNGs or PDF with full Unicode font support
- Camera and gallery QR scanning with multi-file import
- Custom or auto-generated passphrases
- User-selectable quorum (how many shards needed)
- 7 languages: English, Russian, Turkish, Belarusian, Georgian, Ukrainian, Polish
- Cross-platform shard compatibility with the Banana Split web app
Security
Encryption: scrypt key derivation + NaCl secretbox (XSalsa20-Poly1305). Splitting: Shamirs Secret Sharing over GF(256). No data collection, no analytics, no trackers.
Web App
Also available as a web app — no installation needed: https://nfcarchiver.com/banana/
Shards created in the app and web version are fully compatible.
