Easy to use module for signing http requests for ActivityPub using the fetch
API in Node.js

// Headers will automagically get signed
// The `host` and `date` headers will be automatically added

// A `digest` header will be added for verifiers
const response = await fetch(url, {

// You can pass in a custom fetch implementation
// By default globalThis.fetch will be used (node.js 19+)
