RTCPeerConnection.getIdentityAssertion()

The RTCPeerConnection.getIdentityAssertion() method initiates the gathering of an identity assertion. This has an effect only if the signalingState is not "closed".

The method returns a JavaScript Promise which resolves to an identity assertion encoded as a string.

It is not expected for the application dealing with the RTCPeerConnection: this is automatically done; an explicit call only allows to anticipate the need.

pc.getIdentityAssertion();

var pc = new RTCPeerConnection();

pc.setIdentityProvider("developer.mozilla.org");
var assertion = await pc.getIdentityAssertion();
