use chilkat();

# On MacOS or iOS, this searches both the Default keychains and System keychains for the certificate
# having the specified CN.

    print $cert->lastErrorText() . "\r\n";

# Note: In the Apple Keychain, a certificate with its private key represents an identity because it combines the certificate and its private key.
# When Chilkat loads a certificate from the Apple Keychain, it also gets the associated private key.
# You can simply use the cert in other places in Chilkat where a cert w/ private key is required.
