JWT API
A fast, fully-local JSON Web Token toolkit: sign a JSON payload into a JWT, verify a token signature together with its exp and nbf claims using a constant-time comparison, and decode a token header and payload without verifying. Supports the HMAC algorithms HS256, HS384 and HS512, automatically adds the iat claim and an exp claim from expires_in. Built on Node crypto and secrets are never logged, so responses are instant, private and always available. Every endpoint accepts input via the query string or the request body. Ideal for authentication, API gateways, session and token tooling, microservices and webhooks.
