            How to use RSA as kty jwk parameter (using jose4j)
            Asked 2021-Jan-28 at 08:58

            I am using jose4j to encrypt a String with JWE, following this documentation https://bitbucket.org/b_c/jose4j/wiki/JWE%20Examples

            In the example, they used {\"kty\":\"oct\",\"k\":\"Fdh9u8rINxfivbrianbbVT1u232VQBZYKx1HGAGPt2I\"}

            It works well, but how to use RSA as kty ? Should I generate myself a key and put it in the "k" parameter ?

            ANSWER

            Answered 2021-Jan-15 at 10:41

            You can implement a Web API endpoint that will accept your JWE token as an input parameter, decrypts and validates it and returns its payload (contents) as JSON. Then you can easily use JSON in your angular application. In this case you use your signing and encryption keys on the server-side where you keep them in secret.

            Moreover, you may consider using JWT instead of JWE. You decode the token in a public client (angular app) in any case. That is similar to the user_info endpoint of OpenID Connect protocol. Encryption will be useful if you decrypt the token on the server-side (private client).

            Using the signing and encryption keys in the angular application will expose them to the public.

            Alternatively you can introduce another JWT token that is not encrypted and return it to your angular application instead of or in addition to your JWE token. It will be similar to the id_token from OpenID Connect protocol.

            We have a requirement , where we will get modulus from service call to be used for encrypting (JWE) some data at client side

            The decimal string representing the modulus must be converted to a hexadecimal string with the proper formatting. In the following code this is done by the convert function.
            The example encrypts and decrypts a plaintext and is essentially taken from the description of js-jose. The converted modulus is used for the encryption.
            The validity of the conversion can be cross checked e.g. here (and can of course also be concluded from the successful decryption):

            Modify the JwtIssuer ClaimsProvider in the custom policy to achieve the JWE in AD B2C
            Asked 2020-Oct-01 at 07:39

            I am using the AD B2C service for the authentication.

            AD B2C is generating the signed JWT tokens, but the claims information in the JWT token is exposed to the public. If anyone gets the token they can able to see the claims information.

            In my case I need to store some sensitive information in the JWT token. So is there any way to generate JWE token (encrypted token) in AD B2C, so that only the intended recipient can read it.

            Is thre any possible solution to modify the JwtIssuer ClaimsProvider in the custom policy to achieve the JWE. Please suggest

            True JWE with B2C isn’t possible yet. You can send claims to a REST API and send them back to B2C to encrypt them as a stop gap for now.

            ECDH + JWE encryption using nimbus-jose and Java 6
            Asked 2020-Sep-06 at 01:37

            I have a problem and I would like to know if you can help me.

            I need to create an encrypted JWE with elliptic curve.

            i am using

            jre 1.6.0, nimbus-jose-jwt-8.20-jdk6.jar ,bcprov-jdk15to18-166.jar.

            I have created a keystore and a key pair with the EC algorithm and elliptic curve P-512. If I sign the JWT with the private key and then I try to validate it with the public key everything works fine, but apart from signing I need to encrypt to make a JWE in which the payload is not seen.

            When trying to encrypt the JWE with the public key it throws the following Exception

            ANSWER

            Answered 2020-Sep-05 at 12:34

            The problem is that nimbus-jose-jwt-8.20-jdk6.jar does not support being run on Java 6, despite the appearance of 'jdk6' in its name.

            You are getting the error you are seeing because the hashCode() method of the KeyUse class uses a method in the java.util.Objects utility class, and this class is only available from Java 7 onwards.

            I would strongly recommend upgrading from Java 6, to Java 8 at least. Doing so would certainly get around this problem. However, if you are stuck with Java 6, you will have to get in contact with Connect2Id and ask them for support.

            What is correct way to do message formatting and validation?
            Asked 2020-Jul-16 at 07:57

            Situation

            I have Action in my controller that accepts JObject in parameters.

            public IActionResult Test(JObject request)

            For development environment requests will be sent as simple json with data using "application/json" content type.
            But for production environment we will use JWE to protect our data. So request will be JWE token and content type will be "application/jose".

            I create my custom InputFormatter so I can easily read this token, decrypt it and retrieve my JObject to pass it to controllers action. Everything till this moment was ok but I faced problem of sending error message if something wrong with token (e.g. couldn't decrypt because pass phrase is wrong or the token itself is corrupted). InputFormatterResult.Failure() doesn't accept any parameters.

            So I want to understand where should I do this.

            Get Email of User Authenticated in Azure Web App
            Asked 2020-Jul-06 at 05:26

            My Azure Web App written in Node.js is authenticated with the Azure Active Directory and logs in users with their Microsoft Account. I'd like to know the emails of logged in users, and tried to make http get request to /.auth/me endpoint on the client side and server side. However, my last attempt on the server side, I get a 401 code: "{\"code\":401,\"message\":\"IDX12741: JWT: '[PII is hidden]' must have three segments (JWS) or five segments (JWE).\"}".

            I made sure to included the AppServiceAuthSession cookie in my request to the endpoint, and am not sure what I'm doing wrong. I don't have Azure Function enabled, so this is why I'm relying on http requests.

            ANSWER

            Answered 2020-Jul-06 at 05:26

            The AppServiceAuthSession is cookie which is different than a token. If you want to retrieve access token, we need to update the config of Azure app auth settings to make it acquire the access_token for the web API.

            Regarding how to configure it, please refer to the following steps

            1. Login to Resource Explorer

            2. At the top of the page, select Read/Write.

            4. Click Edit.

            5. Modify the following property. Replace with the Azure Active Directory application ID of the service you want to access.

            k is a base64url encoded representation of the octet key, unless the go interface specifically mentions passing keys in JWK format, which it doesn't, you need to provide the raw key. base64url.decode() the k to get the raw key bytes.

            Also, as a sidenote, PBES2-HS256+A128KW is intended to be used with passwords, not keys, given it's computationally heavy i'd recommend a different key wrapping algorithm (not a symmetric passphrase based one). You can use asymmetric crypto to encrypt for a recipient. And if you also want to achieve authentication of the message, don't use key wrapping at all, use the Direct Key Agreement from JWE instead.
