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 Ruby Library

require 'chilkat'



cert = Chilkat::CkCert.new()

success = cert.LoadFromFile("chilkat_cert.pem")
if (success != true)
    print cert.lastErrorText() + "\n"
    exit
end

privkey = Chilkat::CkPrivateKey.new()
success = privkey.LoadPemFile("chilkat_pkey.pem")
if (success != true)
    print privkey.lastErrorText() + "\n"
    exit
end

#  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.new()
#  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() + "\n"
    exit
end

success = cert.LinkPrivateKey("myApp",bMachineKeyset,bForSigning)
if (success != true)
    print cert.lastErrorText() + "\n"
    exit
end

#  Now export to a PFX:
bIncludeCertsInChain = false
success = cert.ExportToPfxFile("chilkat2.pfx","myPassword",bIncludeCertsInChain)
if (success != true)
    print cert.lastErrorText() + "\n"
    exit
end

print "PFX created!" + "\n"
