So your question is on topic There are several techniques to apply or combine depending on your use case 1) Remove the client token from local storage 2) Token blacklist: Store … Read more
I’m afraid the issue comes from the auth configuration in startup. Pls allow me show my code snippet to explain it well. In my opinion, you could use services.AddMicrosoftIdentityWebApiAuthentication(Configuration); instead. And you should exposed the api correctly. The steps of exposing api, you can follow the documents. What I wanna repeat here is when you … Read more
So I was half-step close to the solution, the problem was that while creating const jwtClient = new google.auth.JWT(googleKey.client_email, null, googleKey.private_key, [‘https://www.googleapis.com/auth/gmail.send’], null); i did not mention the account to be impersonated. The correct initialization should be: const jwtClient = new google.auth.JWT(googleKey.client_email, null, googleKey.private_key, [‘https://www.googleapis.com/auth/gmail.send’], ‘[email protected]’); To summarize, the correct steps are: Created a project … Read more
Your Base64 string is not valid. It must be padded with = characters to have a length that is a multiple of 4. In your case: “eyJlbWFp….MTM3fQ==”. With this padding, initWithBase64EncodedString decodes the Base64 string correctly.
The best solution I could put together so far: Grab the certificate (the first value in the x5c property array) from either https://login.microsoftonline.com/common/discovery/keys or https://login.microsoftonline.com/common/discovery/v2.0/keys, matching kid and x5t from the id_token. Wrap the certificate in —–BEGIN CERTIFICATE—–\n and \n—–END CERTIFICATE—– (the newlines seem to matter), and use the result as Public Key (in conjunction … Read more
Here is a full working minimal sample with a controller. I hope you can check it using Postman or JavaScript call. appsettings.json, appsettings.Development.json. Add a section. Note, Key should be rather long and Issuer is an address of the service: … ,”Tokens”: { “Key”: “Rather_very_long_key”, “Issuer”: “http://localhost:56268/” } … !!! In real project, don’t keep … Read more
I like the XSRF Double Submit Cookies method which mentioned in the article that @pkid169 said, but there is one thing that article doesn’t tell you. You are still not protected against XSS because what the attacker can do is inject script that reads your CSRF cookie (which is not HttpOnly) and then make a … Read more
JWT doesn’t have a benefit over using “sessions” per se. JWTs provide a means of maintaining session state on the client instead of doing it on the server. What people often mean when asking this is “What are the benefits of using JWTs over using Server-side sessions“. With server-side sessions, you will either have to … Read more
Using x5c is just one way, but you can also retrieve the public key with the parameters e (public exponent) and n (modulus), which is also documented on the jose-jwt github page: //If kid was found then load public key if (jwkkey != null) { RSACryptoServiceProvider key = new RSACryptoServiceProvider(); key.ImportParameters(new RSAParameters { Modulus = … Read more
Found the reason for my Problem! I just needed to end the filterchain and return the result immediatly if a OPTIONS request is processed by the CorsFilter!
