New here? Start with the Quickstart (top menu). Three entry points:

• @websign/sdk: sign(), certificates(), status(), onChange(), installUrl(), fingerprint() and WebSignError.
• @websign/sdk/messages: errorText(), localized texts for people in 7 languages.
• @websign/sdk/testing: installFakeWebSign(), a fake extension and app for tests and local development. Never ship it.

import { sign } from "@websign/sdk";

const { signature, certificate } = await sign({
  hash: "SHA-256",
  prepare: (certificate, { hash }) => crypto.subtle.digest(hash, signedAttributesFor(certificate)),
});
