TLSNotary

About

TLSNotary lets you create verifiable proofs of website data. It cryptographically confirms what a website told you, without sharing your password or full session.

It is used by developers to build apps that require trusted, tamper-proof data from the web.

⚠ WERE YOU ASKED TO INSTALL THIS?

If an app or website sent you here, pause before continuing.

TLSNotary is a legitimate, open-source tool, but it can be used by third-party plugins to read and share the contents of web pages you visit.
Only proceed if:
• You trust the app or service that directed you here
• You understand what data it is asking you to prove (e.g. your account balance, identity, or transaction history)
• You are comfortable with that data being shared

When in doubt, do not install. You can always verify TLSNotary at: https://tlsnotary.org

TLSNotary is a zkTLS engine for the browser. You write a plugin for your specific use case and TLSNotary handles the infrastructure to run it, request proofs from users, and verify them, without relying on a centralized trusted third party.

✔ Censorship resistant
✔ Open source and auditable
✔ Private: only share what you choose to disclose
