title: How can I calculate the thumbprint of an OpenID Connect server?
body: <p>When creating an OpenID Connect Provider (for e.g. AWS), I need to specify a <em>thumbprint</em> for the connector. What is it, and how do I get it?</p>
  <p>E.g. from <a href="https://stackoverflow.com/questions/69243571/how-can-i-connect-github-actions-with-aws-deployments-without-using-a-secret-key/69243572#69243572">How can I connect GitHub actions with AWS deployments without using a secret key?</a></p>
  <pre><code>resource &quot;aws_iam_openid_connect_provider&quot; &quot;github&quot; {
    url = &quot;https://token.actions.githubusercontent.com&quot;
    client_id_list = [
      &quot;githubactions&quot;,
    ]
    thumbprint_list = [
      &quot;6938fd4d98bab03faadb97b34396831e3780aea1&quot;,
    ]
  }
  </code></pre>
