        // On MacOS and iOS, the LoadByCommonName function will search the Apple Keychain for the matching certificate.

        // A digital certificate's Common Name (CN) is a field in the certificate that specifies the name of the entity the
        // certificate is issued to. It is often used to identify the domain name, hostname, or organization the certificate represents.

        // For example:
        // - In an SSL/TLS certificate for a website, the CN typically contains the domain name (e.g., "www.example.com").
        // - For certificates representing individuals or organizations, the CN might include the person's name or the organization's name.

        // The CN is part of the certificate's Subject field and is crucial for verifying that the certificate corresponds
        // to the intended entity, especially in SSL/TLS communications.
