Function extractProfileFromSocket

extractProfileFromSocket(
    socket: Socket & {
        getCipher?: () => | {
            name?: string;
            standardName?: string;
            version?: string;
        }
        | null;
        getProtocol?: () => string | null;
        getSharedSigalgs?: () => string[];
        isSessionReused?: () => boolean;
    },
): Partial<TlsProfile>
Attempt to read raw TLS properties exposed on a Node.js TLSSocket.

This requires Node.js >= 20 with enableTrace: true or a custom TLS server that exposes socket._tlsConnectState / socket.getPeerCertificate.

Returns a partial TlsProfile with whatever information is available from the socket; most fields typically require a reverse-proxy to inject headers (see createTlsMiddleware).
Parameters
- socket: Socket & {
      getCipher?: () => | {
          name?: string;
          standardName?: string;
          version?: string;
      }
      | null;
      getProtocol?: () => string | null;
      getSharedSigalgs?: () => string[];
      isSessionReused?: () => boolean;
  }
  A tls.TLSSocket from a Node.js HTTPS/TLS server.
Returns Partial<TlsProfile>
