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

cert = chilkat2.Cert()

# 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.
