What is this?

jwt is an npm CLI program for decoding JSON Web Tokens (JWT) and the Unix timestamps within their bowels.

Usage

There are two ways to parse a jwt. Copy the jwt to your clipboard and pipe it into the jwt command, or paste it as an argument.

1. pbpaste | jwt
2. jwt <encoded token> --secret=<optional signing secret> --output=json
