This library supports the parsing and verification as well as the generation and signing of JWTs. Refer to the RFC for information about reserved keys and the proper way to add your own. It's called the Claims and contains the actual stuff you care about. The part in the middle is the interesting bit. For example, which encryption method was used for signing and what key was used. It contains the necessary information for verifying the last part, the signature. The last part is the signature, encoded the same way. The first two parts are JSON objects, that have been base64url encoded. A token is made of three parts, separated by. It's commonly used for Bearer tokens in Oauth 2. In short, it's a signed JSON object that does something useful (for example, authentication). JWT.io has a great introduction to JSON Web Tokens. This library attempts to make it easy to do the right thing by requiring key types match the expected alg, but you should take the extra step to verify it in your usage. SECURITY NOTICE: It's important that you validate the alg presented is what you expect. Recommendation is to upgrade to at least 1.8.3. SECURITY NOTICE: Some older versions of Go have a security issue in the cryotp/elliptic. If you depend on this library and don't want to be interrupted, I recommend you use your dependency mangement tool to pin to version 3. If you have other ideas, or would like to participate in 4.0.0, now's the time. See the 4.0.0 milestone to get an idea of what's coming. 4.0.0 will follow shortly which will include breaking changes. I'm working now on cutting two different releases: 3.2.0 will contain any non-breaking changes or enhancements. NEW VERSION COMING: There have been a lot of improvements suggested since the version 3.0.0 released in 2016.

Including Couchbase in a GraphQL with JWT Application I wouldn’t recommend getting into the JWT side of things until you have an understanding of using GraphQL with Golang. We’re going to see how to handle account creation, JWT validation, and working with live data through GraphQL queries.īefore diving into some design and development, if you haven’t seen my previous tutorials on the subject, you probably should. The logical next step in this GraphQL with Golang journey would be to wire up Couchbase to a fully functional GraphQL powered API that includes authorization with JSON web tokens (JWT). Going a step further we saw how to include JSON web tokens (JWT) for authorization on GraphQL objects, but without a database. First we saw how to get started with GraphQL and Go, followed by an alternative way to handle data relationships by using resolvers on GraphQL objects. Over the past few months I’ve been writing a GraphQL series using the Go programming language.
