# Deprecation notice

PageSigner used an old TLSNotary protocol which is unaudited, experimental, and deprecated. 
A vulnerability was discovered in PageSigner on 19th Jul 2023 allowing the prover to create arbitrary proofs, thus the proofs created with PageSigner must not be trusted.

This repository will not receive any updates and is archived for historical purposes.

------------------------------------------------------------------------------------


//---------------------------------------------------------------------------------//
Update May 2022: We are actively working on a TLSNotary implementation in Rust here:
https://github.com/tlsnotary/tlsn/
When the Rust implementation is ready, it will replace this nodejs-based tool.
//---------------------------------------------------------------------------------//

pgsg-node.js allows you to run PageSigner with nodejs >= v 16.5.0

Clone this repo with:
git clone --recurse-submodules https://github.com/tlsnotary/pagesigner-cli
Install dependencies by running inside the pagesigner-cli directory:
npm ci



Usage: ./pgsg-node.js <command> [arguments]

where <command> is one of notarize, verify

Examples:

./pgsg-node.js notarize example.com --headers headers.txt
Notarize example.com using HTTP headers from headers.txt
The most basic headers file can look like this:

GET /r/worldnews/ HTTP/1.1
Host: www.reddit.com

./pgsg-node.js verify imported.pgsg
Verify a Pagesigner session from imported.pgsg. This will create a session directory with the decrypted cleartext and the copy of the pgsg file.
