PASETO vs JWT: Choosing the Right Token for the Job
A side-by-side deep dive on JWT and PASETO: how each format is structured, the cryptographic primitives involved, JWT's recurring footguns (algorithm confusion, the 'none' attack, JWE neglect), how PASETO's versioned protocols eliminate those bug classes by design, and a Go implementation of both for issuing and verifying tokens.
