How It Works

This patent covers the same core encryption system as Patent 01—an encryption server that generates a sender key, encrypts message content, wraps the sender key with an asymmetric key pair, protects the private key with a master key, and delivers encrypted content to recipients via hyperlinks.

It describes alternative implementation approaches and refined technical specifications for the encryption architecture, representing continued R&D investment in the technology behind Bracket.

What Makes It Different

• Same proven architecture: covers the sender key, asymmetric key pair, master key hierarchy, and hyperlink-based delivery system that powers Bracket.
• Alternative implementations: describes additional approaches to the encryption and delivery process, broadening the technical foundation.
• Refined specifications: deeper technical detail on the key management and message delivery mechanisms.

Why It Matters

Bracket’s encryption system is the result of years of iterative engineering. This patent reflects that ongoing refinement—each cycle of development deepens the technical foundation that makes zero-friction encrypted email possible.
