Do I need to write code like this in my app? Subject = new ClaimsIdentity(new ", key, key ) Īfter you have validate your JWT token, there may be more work in your app/API where you need to check other claims, like scopes and roles, so you can distinguish between a token with scope and. Var tokenDescriptor = new SecurityTokenDescriptor
Var tokenHandler = new JwtSecurityTokenHandler() Public string GenerateJwtToken( string claimName, string claimValue, byte signingKey)
GenerateJwtToken( "id", Guid.NewGuid().ToString(), privateSigningKey ) private byte privateSigningKey = ("This-is-my-magic-private-secret-that-will-be-used-to-sign-a-private-JWT") Symmetric means that it is not one-way and that we can use it for both encrypt AND decrypt. We are passing a key/value pair for the claim ‘id’ and we are also passing a byte array to be used as symmetric key for encryption. The dotnet code for generating this JWT token looks like the below. The other fields, in both the header and the payload, are automatically generated In the below screenshot, we have a self-signed JWT token that was signed with a symmetric key where we added the id, iss and the aud claim just because we can – not that we need to.
You can generate a JWT token yourself without the use of an Identity Provider, like Azure AD B2C, but then it is a bit difficult for the verifier to validate the token unless it shares some secrets with the issuer. I consists of three sections – a header, a payload and a signature – concatenated together with a “.” where each part is a base64 encoded and the first two are in json. What is a JWT Token?Ī JWT Token is defined in RFC7529 and is adequately explained in wikipedia. The github repo for this project can be found here. This blog post contains no information you can’t find in the open standards specifications or in other good blogs out there, but I do feel the need to write it anyway since I do get the question ever so often – how do you validate a JWT token? I will show you and write a very simple dotnet console program to do just that.
