import chilkat cert = chilkat.CkCert() # The LoadByCommonName method searches the registry-based # Windows Current User Certificate Store and Local Machine Certificate # Store for a certificate whose common name (CN) matches # the argument: success = cert.LoadByCommonName("Chilkat Software, Inc.") if (success == False): print "Failed to find certificate!" else: # Display the certificate's distinguished name: print cert.subjectDN() isExpired = cert.get_Expired() if (isExpired == True): print "Certificate is expired." else: print "Certificate is NOT expired." # Alternatively, load a Certificate from a .cer file. # (Certs may also be loaded from other types of files, such as PEM, DER, PFX, etc.) success = cert.LoadFromFile("myCert.cer") if (success == False): print "Failed to load certificate!" else: # Display the certificate's distinguished name: print cert.subjectDN() isExpired = cert.get_Expired() if (isExpired == True): print "Certificate is expired." else: print "Certificate is NOT expired." # The Chilkat Certificate, Certificate Store, Private Key, # Public Key, and Key Container classes / objects are freeware. # They are used by and included with the Chilkat Email, # Crypt, S/MIME, and other commercial Chilkat components. |
