Demonstrates how to export a public key from a USB token or smart card via the Apple Keychain. C

void ChilkatSample(void)
    {
    BOOL success;
    HCkCert cert;

    success = FALSE;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    cert = CkCert_Create();

    // 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.
