MussNV encrypts your files directly in your browser using AES-256-GCM encryption before they ever leave your device. Your encryption key is derived from your password using PBKDF2 with 600,000 iterations, making brute-force attacks impractical. We never see your password, your encryption key, or your unencrypted files.
This zero-knowledge architecture means that even if our servers were compromised, your data would remain protected. Files are split into encrypted chunks for reliable uploads, and each chunk is individually encrypted with a unique nonce.
Share sensitive documents, contracts, medical records, financial statements, or personal photos without trusting a third party with your data. Set expiration times from 1 hour to 7 days, limit the number of downloads, and share the password through a separate channel for maximum security.
MussNV supports single files, multiple files, and entire folders. Built with the Web Crypto API, all encryption and decryption happens client-side in your browser. No software to install, no accounts required for basic transfers.
