• Verifying Cognito access tokens - Comparing three JWT packages for Lambda authorizers

  The Lambda authorizer code decodes and verifies the token, and its business logic determines whether the request should proceed to the backend or be denied. Cognito access tokens are JSON Web Tokens (JWTs), and to simplify our coding, we might opt for an external package to handle token verification. - Source: dev.to / about 1 month ago

• Zero Trust at the Edge (part 4)

  Rerunning the test script, we now see a third piece of information dumped, something that looks remarkably like a JWT. If you copy that token and drop it into https://jwt.io you should see your full token:. - Source: dev.to / 3 months ago

• Zero Trust at the Edge (part 2)

  For simple testing purposes, I went to https://jwt.io/ and changed the "Algorithm" dropdown to RS512. Towards the bottom of the screen, in the "Verify Signature" area, they include both the public and private keys used to sign their sample JWT. I simply copied both into the privkey.pem and pubkey.pem files you see above. - Source: dev.to / 3 months ago

• Zero Trust at the Edge (part 1)

  Https://jwt.io/, a tool created by Auth0/Okta which generates a variety of "dummy" JWTs and allows you to change all three parts of the token and see the effect of those changes. It's an invaluable tool if you're building your own JWT signing service and want to experiment or quickly validate your own tokens. You can also inspect tokens from any other service, even if you can't validate them within this tool. - Source: dev.to / 3 months ago

  If we copy the access token and decode that, I use jwt.io, we can see that my user has the claim cognito:groups that our PEP and PDP will use later for permissions. - Source: dev.to / 3 months ago

• Validation, Authentication and Authorization with Libraries

  On jwt.io, what happens when you add another key value to the payload? Does the signature change? If it changed then it means when an attacker gets an auth token from our platform, they can not replicate it. They have to sign it. Their secret for hashing will not be the same as ours as such our system will not accept it as a valid auth token. For a jwt with a longer TTL, (Time To Live, expiration time), an... - Source: dev.to / 3 months ago

• Building a RESTful API with ASP.NET Core, Swagger, and Neon

  To protect your API endpoints, we’ll use JWT (JSON Web Token) authentication. By adding the [Authorize] attribute to specific controller actions, you can ensure that only authenticated users have access. Here’s how to secure the GetProducts endpoint:. - Source: dev.to / 3 months ago

• Learning JWT security using KumuluzEE — The finances of a league of the environment

  Before we continue, please note that both the Header and the Payload can be decyphered in our example. We just "can’t" tamper with the payload or the header and still make it trusted. The protection against the potential effects of a malicious token can only be protected by the algorithm we choose. So choose wisely. If you are working in an organization where top secret information is a concern, such as a bank,... - Source: dev.to / 4 months ago

• Protecting Applications with Kong security plugins and using StatsD to monitor system states — A healthy camera story

  Iss is the issuer. This issue can be specified and if we don’t, Kong will give us a random one. The issuer is an essential part of the signature, although it is not protected. For every time we ask for a JWT a new secret is generated. The secret for this run was: xwRs1oR22OhzBeq2hWH4NnIxdF5Jr6jv . If we input that in JWT.io we’ll be able to get validated and whatever operation we provide in the payload and in the... - Source: dev.to / 4 months ago
