[SR-Users] STIR/SHAKEN public key

Hello guys, I'm testing with 2 providers right now, and one of them is asking me to include my whole certificate on the *secsipid_add_identity(origTN, destTN, attest, origID, x5u, keyPath)* like: *secsipid_add_identity("$fU", "$rU", "A", "", "https://kamailio.org/stir/$rd/cert.pem <https://kamailio.org/stir/$rd/cert.pem>", "/secsipid/$rd/key.pem");* but it is stated that: *x5u is the HTTP URL referencing to the public key that should be used to verify the signature;* One provider is asking to put the cert there, the other hasn't asked that yet. So i'm a little confused, should the x5u be the actual cert (with its intermediary?) or only the public key? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337
