This is interesting! I've blogged about an OpenSSL-only version in https://www.jvt.me/posts/2019/06/13/pretty-printing-jwt-openssl/ https://www.jvt.me/posts/2019/06/13/pretty-printing-jwt-open... which optionally needs Python, so you can do it with basically 0 new dependencies, if that's what you want :)
