Unseal

Unseal is an encryption service designed to securely time-lock messages or files, ensuring they remain inaccessible until a pre-set time, using end-to-end encryption, zero-knowledge privacy, and blockchain-based verification.

Features

Military-grade encryption

Ensures all content is encrypted directly in your browser using strong symmetric cryptography, guaranteeing no unencrypted data is stored or transmitted.

Zero-knowledge privacy

The encryption key never leaves your device, and even Unseal's servers cannot access your unencrypted content, ensuring complete data privacy.

Tamper-proof time-lock

Uses cryptographic enforcement to set precise unlock times, preventing data access until the exact moment specified by the user.

Blockchain-based anchoring

Anchors time data on a public blockchain, creating immutable timestamps for additional security and verification.

Tamper-resistant links

Generates secure URLs with the decryption key embedded, ensuring the key never reaches the server, maintaining security and integrity.

Secure link sharing

Provides a secure URL containing the decryption key as a fragment, ensuring it is never sent to servers and can only be opened when the designated time arrives.
