![]() Refer to RFC 7519 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. We no longer support building jwt-go with unsupported Go versions, as these contain security vulnerabilities So we will support a major version of Go until there are two newer major releases. Our support of Go versions is aligned with Go's version release policy. 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 1.15 See issue dgrijalva/jwt-go#216 for more detail. SECURITY NOTICE: Some older versions of Go have a security issue in the crypto/elliptic. See dgrijalva/jwt-go#462 for a detailed discussion on this topic. See the MIGRATION_GUIDE.md for more information.Īfter the original author of the library suggested migrating the maintenance of jwt-go, a dedicated team of open source maintainers decided to clone the existing library into this repository. Starting with v4.0.0 this project adds Go module support, but maintains backwards compatibility with older v3.x.y tags and upstream /dgrijalva/jwt-go. NewValidationError(errorText, errorFlags)Ī go (or 'golang' for search engine friendliness) implementation of JSON Web Tokens. ParseWithClaims(tokenString, claims, keyFunc, options) (m) Verify(signingString, signature, key) ![]() (p) ParseWithClaims(tokenString, claims, keyFunc) Do i need to verify the token twice? Is there another way to retrieve this data? It is that bad storing decoded data in req parameters? I do appreciate your time and help.ParseRSAPrivateKeyFromPEMWithPassword(key, password) My friend told me this is a bad idea storing decoded data inside req parameters, but i don't think it is this bad. This way the user_id is stored in req.auth for a short period of time. I think i should avoid verify the same token twice, so in the middleware Authorize after verifying i was saving the user_id (encrypted) inside req.auth and after use it in the controller, i was setting req.auth = null. To access the user_id from MangaController i have to verify the token again. ![]() That's my point, i already decoded the token in Authorize middleware but the decoded data do not persist out of the middleware. In MangaController.store i going to save a new manga, and i need to save in the document the user_id who made the request. In the middleware Authorize("Scan") I verify the jwt token with "jwt.verify", if its valid i going to check if there is a active user with the token id and if his permission allow him to access this route, if so i use next() This is my route: routes.post('/manga/post', Authorize("Scan"), MangaMiddleware.valid_manga_store, MangaController.store) In my NodeJs application im using jwt to manage the user session, inside a jwt token i store user_role and user_id.
