Load @octokit/webhooks-methods directly from esm.sh

<script type="module">
  import {
    sign,
    verify,
    verifyWithFallback,
  } from "https://esm.sh/@octokit/webhooks-methods";
</script>

Node

Install with npm install @octokit/core @octokit/webhooks-methods

import { sign, verify, verifyWithFallback } from "@octokit/webhooks-methods";
await sign("mysecret", eventPayloadString);
// resolves with a string like "sha256=4864d2759938a15468b5df9ade20bf161da9b4f737ea61794142f3484236bda3"

await sign({ secret: "mysecret", algorithm: "sha1" }, eventPayloadString);
// resolves with a string like "sha1=d03207e4b030cf234e3447bac4d93add4c6643d8"

await verify("mysecret", eventPayloadString, "sha256=486d27...");
// resolves with true or false

await verifyWithFallback("mysecret", eventPayloadString, "sha256=486d27...", ["oldsecret", ...]);
// resolves with true or false

Methods
