Tag: Flask jwt install

JWT (JSON web token) has become more and more popular in web development. It is an open standard which allows transmitting data between parties as a JSON object in a secure and compact way . The data transmitting using JWT between parties are digitally signed so that it can be easily verified and trusted.

In short, JWTs are used as a secure way to authenticate users and share information . Typically, a private key, or secret, is used by the issuer to sign the JWT. The receiver of the JWT will verify the signature to ensure that the token hasn’t been altered after it was signed by the issuer.

In its simplest form, there is not much to using this extension. You use create_access_token() to make JSON Web Tokens, jwt_required() to protect routes , and get_jwt_identity() to get the identity of a JWT in a protected route. We can see this in action using HTTPie.

class flask_jwt_extended. JWTManager(app=None)[source] An object used to hold JWT settings and callback functions for the Flask-JWT-Extended extension . Instances of JWTManager are not bound to specific apps, so you can create one in the main body of your code and then bind it to your app in a factory function.

Both jwt and flask session work on client , but the key difference is that flask session stores the signed session data at the client cookie, but in jwt you have the independence to store the token anywhere you want, say localstorage, cookie etc.
