JSON Web Tokens (JWTs) are ubiquitous in modern web development, offering a stateless way to handle authentication. However, their security relies entirely on the strength of the signing key. This deep dive explores the mechanics of JWT signing, specifically the HMAC-SHA256 algorithm, and demonstrates how attackers can brute-force weak secrets to forge admin tokens. We provide actionable best practices for secret key length and entropy, and show you how to generate cryptographically strong keys to secure your applications.
