Load Certificate from PFX (PKCS#12)

See more Certificates Examples

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

import sys
import chilkat

success = False

cert = chilkat.CkCert()

# Load from the PFX file
pfxFilename = "/Users/chilkat/testData/pfx/chilkat_ssl_pwd_is_test.pfx"
pfxPassword = "test"

# 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)
if (success == False):
    print(cert.lastErrorText())
    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())

privKey = chilkat.CkPrivateKey()
success = cert.GetPrivateKey(privKey)
if (success == False):
    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"
pemPath = "/Users/chilkat/testData/pem/chilkat_privKey.pem"
success = privKey.SavePkcs8EncryptedPemFile(pemPassword,pemPath)
if (success == False):
    print(privKey.lastErrorText())
    sys.exit()

print("Private key saved to PKCS8 Encrypted PEM...")
