anon.li Drop is a browser-based, end-to-end encrypted file sharing service. Encryption and decryption are performed entirely on the client side using AES-256-GCM, meaning the service provider never has access to file contents, file names, or decryption keys. Key characteristics: - Encryption occurs in the browser before any data is transmitted to the server - File names and optional drop titles are encrypted alongside file contents - Recipients can decrypt files in their browser without creating an account - The encryption key is embedded in the share link, ensuring only the sender and recipient can access the content File transfer capabilities: - Supports multi-file uploads - Smart chunking for large files - Files up to 250GB supported on the Pro tier Access and sharing controls: - Password protection adds an additional authentication layer; recipients need both the link and the password to decrypt - Expiry settings allow auto-deletion after a set time period - Download limits allow auto-deletion after a specified number of downloads - Links can be disabled or re-enabled from the dashboard - QR code generation for share links Account and key management: - A free account tier is available - Vault Key Recovery uses wrapped owner keys so the dashboard can recover share links without exposing plaintext keys to the provider Privacy posture: - Zero-knowledge architecture: the provider cannot access file contents - No tracking or ads - GDPR compliant - Open-source encryption implementation
