certStore = chilkat.CkCertStore()

#  Load the PFX file into a certificate store object

password = "myPassword"

    print certStore.lastErrorText()
    sys.exit()

#  Find the cert to be exported by the subject:

# cert is a CkCert
cert = certStore.FindCertBySubject("Chilkat Software, Inc.")
if (cert == None ):
    print "Certificate not found."
    sys.exit()

#  Does this cert have a private key?
if (cert.HasPrivateKey() == True):

    #  Get the private key.

    # pvkey is a CkPrivateKey
    pvkey = cert.ExportPrivateKey()

    #   Export the private key to a PEM file:
    success = pvkey.SaveRsaPemFile("chilkat_pkey.pem")
    if (success != True):
        print pvkey.lastErrorText()
        sys.exit()

#  Save the cert to a PEM file:
success = cert.ExportCertPemFile("chilkat_cert.pem")
