Hades Auth

Hades Auth is a client-side authentication library (v1.0.63) that uses elliptic-curve cryptography (ECDSA with P-384) for public/private key identity. It provides functions to generate key pairs, onboard devices, sign requests, and wrap fetch calls with signed headers. Unlike token-based auth (JWT/sessions), it never sends secrets to the server; only public keys are stored, making database leaks less catastrophic. The library is ESM-only, ships TypeScript definitions, and is actively released on npm. It is designed for browser use (uses Web Crypto API) and includes a fetch wrapper that automates request signing. The package is maintained by OracularHades.
