Hi All,

We are working on OpenID Connect Conformance Testing, using the test suite
provided in link [1].

The current requirement we have is, exposing the Public Certificate via
jwks.json ('jwks_uri'). We followed the 'jwks_uri'[2] of 'Google OAuth2
cert' and designed following jwks.json file to expose the public
certificate of our server.



{
 "keys": [
  {
   "kty": "RSA",
   "alg": "RS256",
   "use": "sig",
   "n": 
"94A7FA15D6F59CF3F4E4412880BD3A2EB0CCCE3386AC0768A5B6BD902A8CE78B969516EF35F0CA4E2D922BF0B3274F35A5949BEF680E510007696C409BFB8F058DB05ED21B1E51D3791E9C2F9C7FC35BC65C706BE4E7723A3ABABB84B0AFD591EDB8E0A8920873FC04EB8723EAF9092D31F5E7452E07ACA1894F3C5A09C53B39",
   "e": "65537"
  }
 ]
}


To get the modulus and the exponent values for the Public Key, we have
followed post [3].

After doing all these, when running the test suite, the signature
validation fails. What I feel is the "n" and "e" values we have set are not
is proper encoding/encryption. Seems this is not the format in google cert
[2].


   - Do you have any clue on how to get the modulus and the exponent values
   for a Public Key, in proper format ?
   - Have anyone came across similar requirement earlier?
