+/// Using pinned certificates or public keys for evaluation helps prevent man-in-the-middle (MITM) attacks and other
+/// vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged
+/// to route all communication over an HTTPS connection with pinning enabled.

+/// - performDefaultEvaluation: Uses the default server trust evaluation while allowing you to control whether to
+///                             validate the host provided by the challenge. Applications are encouraged to always
+///                             validate the host in production environments to guarantee the validity of the server's

+///                             considered valid if one of the pinned certificates match one of the server certificates.
+///                             By validating both the certificate chain and host, certificate pinning provides a very
+///                             secure form of server trust validation mitigating most, if not all, MITM attacks.
+///                             Applications are encouraged to always validate the host and require a valid certificate
+///                             chain in production environments.
