# certObj is a CkCert
certObj = email.GetSignedByCert()
if (email.get_LastMethodSuccess() == False):
    print(email.lastErrorText())
    sys.exit()

#  Do the equivalent using LastSignerCert.
#  Your application creates a new, empty Cert object which is passed 
#  in the last argument and filled upon success.
