<h1 id="jwt-login-type"><a class="header" href="#jwt-login-type">JWT Login Type</a></h1>
|
||
|
|
<p>Synapse comes with a non-standard login type to support
|
||
|
|
<a href="https://en.wikipedia.org/wiki/JSON_Web_Token">JSON Web Tokens</a>. In general the
|
||
|
|
documentation for
|
||
|
|
<a href="https://matrix.org/docs/spec/client_server/r0.6.1#login">the login endpoint</a>
|
||
|
|
is still valid (and the mechanism works similarly to the
|
||
|
|
<a href="https://matrix.org/docs/spec/client_server/r0.6.1#token-based">token based login</a>).</p>
|
||
|
|
<p>To log in using a JSON Web Token, clients should submit a <code>/login</code> request as
|
||
|
|
follows:</p>
|
||
|
|
<pre><code class="language-json">{
|
||
|
|
"type": "org.matrix.login.jwt",
|
||
|
|
"token": "<jwt>"
|
||
|
|
}
|
||
|
|
</code></pre>
|
||
|
|
<p>The <code>token</code> field should include the JSON web token with the following claims:</p>
|
||
|
|
<ul>
|
||
|
|
<li>A claim that encodes the local part of the user ID is required. By default,
|
||
|
|
the <code>sub</code> (subject) claim is used, or a custom claim can be set in the
|
||
|
|
configuration file.</li>
|
||
|
|
<li>The expiration time (<code>exp</code>), not before time (<code>nbf</code>), and issued at (<code>iat</code>)
|
||
|
|
claims are optional, but validated if present.</li>
|
||
|
|
<li>The issuer (<code>iss</code>) claim is optional, but required and validated if configured.</li>
|
||
|
|
<li>The audience (<code>aud</code>) claim is optional, but required and validated if configured.
|
||
|
|
Providing the audience claim when not configured will cause validation to fail.</li>
|
||
|
|
</ul>
|
||
|
|
<p>In the case that the token is not valid, the homeserver must respond with
|
||
|
|
<code>403 Forbidden</code> and an error code of <code>M_FORBIDDEN</code>.</p>
|
||
|
|
<p>As with other login types, there are additional fields (e.g. <code>device_id</code> and
|
||
|
|
<code>initial_device_display_name</code>) which can be included in the above request.</p>
|
||
|
|
<h2 id="preparing-synapse"><a class="header" href="#preparing-synapse">Preparing Synapse</a></h2>
|
||
|
|
<p>The JSON Web Token integration in Synapse uses the
|
||
|
|
<a href="https://docs.authlib.org/en/latest/index.html"><code>Authlib</code></a> library, which must be installed
|
||
|
|
as follows:</p>
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<p>The relevant libraries are included in the Docker images and Debian packages
|
||
|
|
provided by <code>matrix.org</code> so no further action is needed.</p>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p>If you installed Synapse into a virtualenv, run <code>/path/to/env/bin/pip install synapse[jwt]</code> to install the necessary dependencies.</p>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p>For other installation mechanisms, see the documentation provided by the
|
||
|
|
maintainer.</p>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>To enable the JSON web token integration, you should then add a <code>jwt_config</code> option
|
||
|
|
to your configuration file. See the <a href="usage/configuration/config_documentation.html#jwt_config">configuration manual</a> for some
|
||
|
|
sample settings.</p>

||

<h2 id="how-to-test-jwt-as-a-developer"><a class="header" href="#how-to-test-jwt-as-a-developer">How to test JWT as a developer</a></h2>
|
||
|
|
<p>Although JSON Web Tokens are typically generated from an external server, the
|
||
|
|
example below uses a locally generated JWT.</p>
|
||
|
|
<ol>
|
||
|
|
<li>
|
||
|
|
<p>Configure Synapse with JWT logins, note that this example uses a pre-shared
|
||
|
|
secret and an algorithm of HS256:</p>
|
||
|
|
<pre><code class="language-yaml">jwt_config:
|
||
|
|
enabled: true
|
||
|
|
secret: "my-secret-token"
|
||
|
|
algorithm: "HS256"
|
||
|
|
</code></pre>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p>Generate a JSON web token:</p>
|
||
|
|
<p>You can use the following short Python snippet to generate a JWT
|
||
|
|
protected by an HMAC.
|
||
|
|
Take care that the <code>secret</code> and the algorithm given in the <code>header</code> match
|
||
|
|
the entries from <code>jwt_config</code> above.</p>
|
||
|
|
<pre><code class="language-python">from authlib.jose import jwt
|
||
|
|
|
||
|
|
header = {"alg": "HS256"}
|
||
|
|
payload = {"sub": "user1", "aud": ["audience"]}
|
||
|
|
secret = "my-secret-token"
|
||
|
|
result = jwt.encode(header, payload, secret)
|
||
|
|
print(result.decode("ascii"))
|
||
|
|
</code></pre>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p>Query for the login types and ensure <code>org.matrix.login.jwt</code> is there:</p>
|
||
|
|
<pre><code class="language-bash">curl http://localhost:8080/_matrix/client/r0/login
|
||
|
|
</code></pre>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p>Login used the generated JSON web token from above:</p>
|
||
|
|
<pre><code class="language-bash">$ curl http://localhost:8082/_matrix/client/r0/login -X POST \
|
||
|
|
--data '{"type":"org.matrix.login.jwt","token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ0ZXN0LXVzZXIifQ.Ag71GT8v01UO3w80aqRPTeuVPBIBZkYhNTJJ-_-zQIc"}'
|
||
|

{
|

|
|
"access_token": "<access token>",
|
||
|
|
"device_id": "ACBDEFGHI",
|

|

</code></pre>

</ol>
|
