<p>This guide will take you through the steps of:</p>
<ul>
<li>starting a <code>Notary</code> server</li>
<li>running a <code>Prover</code> to notarize some web data</li>
<li>running a <code>Verifier</code> to verify the notarized data</li>
</ul>
<p>Note that the TLSNotary protocol assumes that the <code>Notary</code> is trusted by the <code>Verifier</code>. To minimize the trust, the <code>Verifier</code> itself can act as a <code>Notary</code>.</p>
<h1 id="preliminaries"><a class="header" href="#preliminaries">Preliminaries</a></h1>
<h3 id="install-rust"><a class="header" href="#install-rust">Install rust</a></h3>
<p>If you don't have <code>rust</code> installed yet, install it with <a href="https://rustup.rs/">rustup</a>:</p>
<pre><code class="language-shell">curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
</code></pre>
<h1 id="guide"><a class="header" href="#guide">Guide</a></h1>
<h3 id="start-a-notary-server"><a class="header" href="#start-a-notary-server">Start a Notary server:</a></h3>
<pre><code class="language-shell">git clone https://github.com/tlsnotary/notary-server
cd notary-server
cargo run --release
</code></pre>
<p>The <code>Notary</code> server will now be running in the background waiting for connections from a <code>Prover</code>. You can switch to another console to run the <code>Prover</code>.</p>
<p>For more information on how to configure the <code>Notary</code> server, please refer to <a href="https://github.com/tlsnotary/notary-server#running-the-server">this</a>.</p>
<h3 id="run-a-simple-prover"><a class="header" href="#run-a-simple-prover">Run a simple Prover:</a></h3>
<pre><code class="language-shell">git clone https://github.com/tlsnotary/tlsn
cd tlsn/tlsn/examples
cargo run --release --example simple_prover
</code></pre>
<p>The notarization session usually takes a few moments and the resulting proof will be written to the &quot;proof.json&quot; file. The proof can then be passed on to the <code>Verifier</code> for verification.</p>
<p>The <code>simple_prover</code> notarizes <a href="https://example.com">https://example.com</a> and redacts the <code>USER_AGENT</code> HTTP header from the proof for the <code>Verifier</code>. You can change the code in <code>tlsn/tlsn/examples/simple_prover.rs</code> to meet your needs:</p>
<ul>
<li>change which server the <code>Prover</code> connects to</li>
<li>add or remove HTTP request headers</li>
<li>redact other strings in the request or the response</li>
</ul>
<p>⚠️ Please note that by default the <code>Notary</code> server expects that the cumulative size of the request and the server response is not more than 16KB.</p>
<h3 id="run-a-simple-verifier"><a class="header" href="#run-a-simple-verifier">Run a simple Verifier:</a></h3>
<pre><code class="language-shell">cargo run --release --example simple_verifier
</code></pre>
<p>This will verify the proof from the <code>simple_prover</code> (<code>proof.json</code>) and output the result to the console.</p>
<p>Note how the parts which the prover chose not to disclose will be shown as &quot;X&quot;:</p>
<pre><code class="language-plaintext">GET / HTTP/1.1
host: example.com
accept: */*
accept-encoding: identity
connection: close
user-agent: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
