Frequently Asked Questions
What is PASETO?
PASETO (Platform-Agnostic Security Tokens) is a secure alternative to JOSE (JWT, JWS, JWE). It's designed to avoid the common security pitfalls of JWT by providing 'golden' cryptographic defaults.
Why use PASETO v4?
Version 4 (v4) of PASETO uses modern, fast, and secure primitives like Ed25519 for signing and XChaCha20-Poly1305 for symmetric encryption.
What is the 'footer' in PASETO?
The footer is an optional, unencrypted part of the token that can carry additional metadata. It's often used for key identification or non-sensitive context.
