# 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.

success = cert2.LoadByCommonName("Chilkat Software, Inc.")
if (success == False):
    print(cert2.LastErrorText)
