RTCCertificateStats

{{APIRef("WebRTC")}}

The RTCCertificateStats dictionary of the WebRTC API is used to report information about a certificate used by an {{domxref("RTCDtlsTransport")}} and its underlying {{domxref("RTCIceTransport")}}.

The report can be obtained by iterating the {{domxref("RTCStatsReport")}} returned by {{domxref("RTCPeerConnection.getStats()")}} until you find an entry with the type of certificate.

Instance properties

• {{domxref("RTCCertificateStats.fingerprint", "fingerprint")}}
  • : A string containing the certificate fingerprint, which is calculated using the hash function specified in fingerprintAlgorithm.
• {{domxref("RTCCertificateStats.fingerprintAlgorithm", "fingerprintAlgorithm")}}
  • : A string containing the hash function used to compute the certificate fingerprint, such as "sha-256".
• {{domxref("RTCCertificateStats.base64Certificate", "base64Certificate")}}
  • : A string containing the base-64 representation of the DER-encoded certificate.

Common instance properties

The following properties are common to all WebRTC statistics objects (See RTCStatsReport for more information).

• {{domxref("RTCCertificateStats.id", "id")}}
  • : A string that uniquely identifies the object that is being monitored to produce this set of statistics.
• {{domxref("RTCCertificateStats.timestamp", "timestamp")}}
  • : A {{domxref("DOMHighResTimeStamp")}} object indicating the time at which the sample was taken for this statistics object.
• {{domxref("RTCCertificateStats.type", "type")}}
  • : A string with the value "certificate", indicating the type of statistics that the object contains.

Examples

Given a variable myPeerConnection, which is an instance of {{domxref("RTCPeerConnection")}}, the code below uses await to wait for the statistics report, and then iterates it using RTCStatsReport.forEach(). It then filters the dictionaries for just those reports that have the type of certificate and logs the result.

const stats = await myPeerConnection.getStats();

stats.forEach((report) => {
  if (report.type === "certificate") {
    // Log the certificate information
    console.log(report);
  }
});
