Building A Secure Signed JWT
JSON Web Tokens (JWTs)_ get a lot of hate online for being insecure. Tom Ptacek, founder of Latacora, a security consultancy, had this to say about JWTs in 2017: So, as someone who does some work in crypto engineering, arguments about JWT being problematic only if implementations are “bungled” or developers are “incompetent” are sort of an obvious “tell” that the people behind those arguments aren
JWT is Awesome: Here’s Why
Here’s my take on JWT* and why I think it’s amazing, after having migrated hundreds of applications in JP Morgan from a legacy authentication solution. *JWT = JSON Web Token 1) Pro: JWT is standardized and supported in most languages For applications to have authentication, this requires developers to tightly integrate authentication when writing the application. Authentication code is tough work
The Ultimate Guide to handling JWTs on frontend clients (GraphQL)
The Ultimate Guide to handling JWTs on frontend clients (GraphQL) JWTs (JSON Web Token, pronounced 'jot') are becoming a popular way of handling auth. This post aims to demystify what a JWT is, discuss its pros/cons and cover best practices in implementing JWT on the client-side, keeping security in mind. Although, we’ve worked on the examples with a GraphQL clients, but the concepts apply to any
JWT形式を採用したChatWorkのアクセストークンについて - ChatWork Creator's Note
JWTを使うことは難しい？ こんにちは、かとじゅん(@j5ik2o)です。最近、JWTに関する以下のブログが話題です*1。 どうしてリスクアセスメントせずに JWT をセッションに使っちゃうわけ？ - co3k.org このブログで言及されているのは、JWTをセッションの保存先に選ぶことで「何が問題なの？」に書かれているリスクがあるよ、という話*2。確かにいくつか検討することがありますね。 auth0.hatenablog.com auth0の中の人？よくわからないけど、反論的なブログエントリが公開されています。この記事では、指摘の問題が起こらないように設計するのはあたり前では？という意見みたいです。まぁごもっともではないでしょうか。 私も技術そのものというより、要件に合わせて技術を組み合わせる設計の問題だと思っています。加えて、JWTを利用することはそんなに難しいことかという疑問があった
Big Sky :: ログイン認証をマイクロサービス化する「loginsrv」
認証を持たないウェブアプリケーションをいざ認証に対応させようと思うと案外面倒でモチベーションを無くしてしまうなんて事もよく起きうる話です。特に社内向けのアプリケーションを作っていたら本番で使う事になってしまって、なんて話は良くある話です。開発で本番 DB を見るのはちょっと...。でも既存のコードをゴリゴリと触りたくない。そんな場合にログイン認証部分だけマイクロサービス化できると気持ちも幾分和らぎます。今日はそんなちょっと便利なサーバ「loginsrv」を紹介したいと思います。 GitHub - tarent/loginsrv: JWT login microservice with plugable backends such as OAuth2, Github, htpasswd, osiam loginsrv is a standalone minimalistic login se
Things to Use Instead of JWT | Kevin Burke
You might have heard that you shouldn't be using JWT. That advice is correct - you really shouldn't use it. In general, specifications that allow the attacker to choose the algorithm for negotiation have more problems than ones that don't (see TLS). N libraries need to implement M different encryption and decryption algorithms, and an attacker only needs to find a vulnerability in one of them, or
Brute Forcing HS256 is Possible: The Importance of Using Strong Keys in Signing JWTs
VulnerabilitiesBrute Forcing HS256 is Possible: The Importance of Using Strong Keys in Signing JWTsCracking a JWT signed with weak keys is possible via brute force attacks. Learn how Auth0 protects against such attacks and alternative JWT signing methods provided. JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties. They can be digita
