Create PFX from PEM (Certificate and Private Key Files)

Create a PFX file from a pair of PEM files (the certificate PEM and private key PEM).

Download Chilkat Python Library

import sys
import chilkat



cert = chilkat.CkCert()

success = cert.LoadFromFile("chilkat_cert.pem")
if (success != True):
    print cert.lastErrorText()
    sys.exit()

privkey = chilkat.CkPrivateKey()
success = privkey.LoadPemFile("chilkat_pkey.pem")
if (success != True):
    print privkey.lastErrorText()
    sys.exit()

#  Link the cert to the private key.
#  Use the current logged-on user's protected key store:
bMachineKeyset = False
#  If the private key is to be used for creating signatures,
#  set bForSigning = True.  If the private key is to be
#  used for decrypting, set bForSigning = False
bForSigning = True

#  Select an arbitrary key container name that is unique
#  to your application.  Make sure it exists:
keyCont = chilkat.CkKeyContainer()
#  The CreateContainer method will create the key container
#  if it does not already exist, otherwise it will open it.
#  (The key container is in the Windows protected store.)
success = keyCont.CreateContainer("myApp",bMachineKeyset)
if (success != True):
    print keyCont.lastErrorText()
    sys.exit()

success = cert.LinkPrivateKey("myApp",bMachineKeyset,bForSigning)
if (success != True):
    print cert.lastErrorText()
    sys.exit()

#  Now export to a PFX:
bIncludeCertsInChain = False
success = cert.ExportToPfxFile("chilkat2.pfx","myPassword",bIncludeCertsInChain)
if (success != True):
    print cert.lastErrorText()
    sys.exit()

print "PFX created!"
