Jwt decode npm10/31/2023 How to implement JWT Signature Periodic Key RotationĪ JSON Web Token (or JWT) is simply a JSON payload containing a particular claim.RS256 vs HS256 Signatures - Which one is better?.The RS256 JWT Signature - let's talk about public key crypto.The HS256 JWT Signature - How does it work?.User Session Management with JWTs: Subject and Expiration.JWTs in a Nutshell: Header, Payload, Signature.In this post we are going to cover the following topics: The authentication server can issue the token, send it back and then immediately discard it!Īlso, there is also no need to store password digests at the level of the application database either, so fewer things to get stolen and less security-related bugs.Īt this point you might be thinking: I have an in-house internal application, are JWTs a good solution for that as well? Yes, in the last section of this post we will cover the use of JWTs in a typical Pre-Authentication enterprise scenario. The external authentication server can be completely separate from our application server and does not have to share any secret key with other elements of the network, namely with our application server - there is no secret key installed on our server to be accidentally lost or stolen.Īlso, there is no need for any direct live link between the authentication server or the application server for authentication to work (more on that later).įurthermore, the application server can be completely stateless, as there is no need to keep tokens in-memory between requests. or even a completely external third-party authentication provider such as for example Auth0.
