Create a JsonWebKey from JSON

Question

I have a url that has my jwks values. It looks like this

{
  "keys": [
   {
       "kty": "RSA",
       "e": "AQAB",
       "use": "sig",
       "kid": "Has a Real Value Here",
       "alg": "RS256",
       "n": "Has a Real Value here"
   }]
}

I tried to take that json, and feed it into the JsonWebKey constructor like this:

HttpClient client = new HttpClient();
var response = client.GetAsync("https://myIdp/oauth2/jwks").Result;
var jwksString = response.Content.ReadAsStringAsync().Result;

publicJwk = new JsonWebKey(jwksString);

When I do that, none of the values in the class get populated. The thing that gets a value is a AdditionalData field. It gets all to the json put there.

Is there a way to get the JsonWebKey constructor to actually parse out the Json?

the jwks values are array so you need to you jsonwebkeyset which is an collection of jsonwebkey. something like this:

HttpClient client = new HttpClient();
var response = client.GetAsync("https://myIdp/oauth2/jwks").Result;
var jwksString = response.Content.ReadAsStringAsync().Result;

jwkset = new JsonWebKeySet(jwksString);
