jwt-go VS libgossamer

My only suggestion, because I haven't seen anyone else mention it, is researching your dependencies. In the app you're using https://github.com/dgrijalva/jwt-go, which isn't maintained anymore and in their repo they state that you should use https://github.com/golang-jwt/jwt instead.

There are so many tools created tools using golang like the gh-cli, cockrach-db, jwt, etc. You can see a whole list of applications/tools/frameworks written in Go from this awesome list

If it is using "github.com/golang-jwt/jwt" under the hood than all you have to do is override the Valid() method on your claims object.

The code logic is query user record from database by input parameter username, if not found, return Incorrect username or password error, if password was correct, issue token. The jwt library used here is golang-jwt/jwt

Abandon https://github.com/dgrijalva/jwt-go library due security issues. Now I use https://github.com/golang-jwt/jwt#jwt-go

Use jwt (jwt.io, https://github.com/golang-jwt/jwt) shoveling the params into a MapClaims.

Go JWT Implementation Link

The boilerplate application uses the dgrijalva / jwt-go library to work with JWTs. Besides the standard set of claims fields, this library allows you to describe additional fields. In the application, this makes it possible to write to the token the ID of the user to whom it was issued. The library supports the NewWithClaims () and Parse () functions used in the AuthHandler application to create and validate tokens. Also, the Echo framework has a JWT middleware that uses the specified library to validate tokens. This middleware is hooked up in the ConfigureRoutes () function of the template application that declares the routing.

There might be many different packages, but I think this one is the most popular: https://github.com/dgrijalva/jwt-go. So let’s copy its URL, and run go get in the terminal to install the package:

See the definition of AppendKey:

That's why Gossamer exists, though. (I would talk about it more on here, but I figured everyone's still sick of hearing about it.) :)

Anyway, Github is still online -- https://github.com/paragonie/libgossamer

More recently, I wrote a blog post about end-to-end encryption, and mentioned integrating with some sort of decentralized authority-free identity system like Gossamer.
