(CkPython) Load Certificate from PFX (PKCS#12)

Loads a digital certificate (and private key, if available) from a PFX file.(also known as PKCS#12)

# A PFX typically contains certificates in the chain of authentication.
# The Chilkat cert object will choose the certificate w/
# private key farthest from the root authority cert.
# To access all the certificates in a PFX, use the 
# Chilkat certificate store object instead.
success = cert.LoadPfxFile(pfxFilename,pfxPassword)

    sys.exit()

# Get some information about the digital certificate, 
# then get the private key...

# DN = "Distinguished Name"
print("SubjectDN:" + cert.subjectDN())

print("Common Name:" + cert.subjectCN())
print("Issuer Common Name:" + cert.issuerCN())

print("Serial Number:" + cert.serialNumber())

# Now for the private key...

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

    print(cert.lastErrorText())
    sys.exit()

# The private key object may be used in any Chilkat methods
# (in other objects/classes) that expect a private key argument.

# In this case, save the private key to a PKCS8 Encrypted PEM format file:
pemPassword = "secret"
