@uuaid/core

Cryptographic primitives for UUAID — the identity + certification layer for AI agents ("the SSL/CA for agents").

• UUAID grammar — mint + parse uuaid:<namespace>:<type>:<uuidv7> (durable, creation-time-ordered agent identifiers).
• JCS canonicalization (RFC 8785) + contentHash — stable, on-chain-ready content hashes for any JSON value.
• Crypto-agile signature envelope — Ed25519 today; ml-dsa-65 / slh-dsa-128s reserved. Hybrid = multiple signatures over one payload in a single envelope.

import { mintUuaid, contentHash, generateEd25519, sealEnvelope, verifyEnvelope } from "@uuaid/core";

const agent = mintUuaid("agent");            // { uuaid, uuid }
const signer = generateEd25519();
const env = sealEnvelope({ hello: "world" }, [{ key: signer, keyId: "k1" }]);
verifyEnvelope(env);                          // { valid: true, verified: 1, total: 1 }
