tlsn-js

NPM Modules for proving and verifying using TLS Notary in the browser.

The prover requires a notary-server and websockify proxy

Example

import { prove, verify } from '../src';

// To create a proof
const proof = await prove('https://swapi.dev/api/people/1', {
    method: 'GET',
    headers: {
      Connection: 'close',
      Accept: 'application/json',
      'Accept-Encoding': 'identity',
    },
    body: '',
    maxTranscriptSize: 20000,
    notaryUrl: 'https://127.0.0.1:7047',
    websocketProxyUrl: 'ws://127.0.0.1:55688',
});

// To verify a proof
const result = await verify(proof);
console.log(result);

Running a local websockify proxy for https://swapi.dev

git clone https://github.com/novnc/websockify && cd websockify
./docker/build.sh
docker run -it --rm -p 55688:80 novnc/websockify 80 swapi.dev:443

Install as NPM Package

npm install tlsn-js

Development

[!IMPORTANT] Note on Rust-to-WASM Compilation: This project requires compiling Rust into WASM, which needs clang version 16.0.0 or newer. MacOS users, be aware that Xcode's default clang might be older. If you encounter the error No available targets are compatible with triple "wasm32-unknown-unknown", it's likely due to an outdated clang. Updating clang to a newer version should resolve this issue.
