Hi all,
We receive this error in the log file, "JWT could not be decrypted", and I give
details below, we would need a bit of help to figure out the cause of the error.
In my understanding the IdP exposes an http endpoint called jwks where the set
of keys and associated encryption types (symmetric or asymettric) and
algorithms (e.g. RSA with SHA256).
Then when e.g. the token endpoint responds with some JWT tokens (id, access,
refresh), then httpd oidc module tries the keys with algos until one succeeds.
Our jwks endpoint returns:
{
"keys": [
{
"kty": "RSA",
"use": "sig",
"alg": "RS256",
"n": "..",
"e": ".."
}
]
}
All the errors in the log are, in order:
[auth_openidc:error] oidc_util_jwt_verify: parsing JWT failed: [src/jose.c:694:
oidc_jwe_decrypt_impl]: encrypted JWT could not be decrypted with any of the 1
keys: error for last tried key is: crypto error [file: jwe.c, function:
_cjose_jwe_decrypt_dat_a256gcm, line: 1031]
[auth_openidc:error] oidc_authorization_response_match_state: unable to restore
state
[auth_openidc:error] oidc_handle_authorization_response: invalid authorization
response state and no default SSO URL is set, sending an error..
As a side note, we are behind a corporate firewall with basic auth and I
configured it with ProxtRemote and sending Authorization Basic header manually
on all requests. It seems to be passed over the previous errr (connection
timeout) so I think it connects well to IdP.
As another side note, I am doing part of the flow in browser and part of it in
curl (because in some requests I need to go through an http proxy, while in
others I need to use the proxy, and the browser is forced into proxy usage for
security reasons). So there may be some cookies or other things missing, as a
potential cause.
Could you help me how to investigate the cause of the error below?
Thank you very much,
