How Zero-Knowledge Temporary File Sharing Works
Zero registration • Hardware AES-256-GCM encryption • 24-hour automatic self-destruct
01
In-Browser Encryption
Add files up to 50 MB. Your browser encrypts the raw bytes in hardware memory with AES-256-GCM before transmission.
02
Key in URL Hash
The decryption key is placed into the link hash fragment (#key=...). Our servers only store unreadable encrypted ciphertext.
03
24-Hour Self-Destruct
The recipient downloads and decrypts the file on their device. Once 24 hours elapse, the ciphertext is permanently purged.
