Quickstart

This illustrative example creates a prefixed key and its digest, then stores the digest. Give the plaintext key only to its authorized recipient, once:

import { generateKeyAndHash } from "@fungi.computer/one-key";

// Stand-in for the credential owner's real storage operation. One Key does
// not provide storage.
async function storeCredentialDigest(digest: string): Promise<void> {
  console.log("store this digest:", digest);
}

const { key, digest } = await generateKeyAndHash({ prefix: "invite" });
await storeCredentialDigest(digest);
console.log("send this key to its recipient once:", key);

The existing tests verify that a generated digest matches the plaintext key in test/crypto.test.ts.
