(CkPython) Use HTTPS Client Certificate from .cer and .key Files

Demonstrates how to load a cert + private key from .cer and .key (base64) files and use it for mutual TLS authentication (client-side certificate).

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = chilkat.CkHttp()

cert = chilkat.CkCert()
privKey = chilkat.CkPrivateKey()

# Load any type of certificate (.cer, .p7b, .pem, etc.) by calling LoadFromFile.
success = cert.LoadFromFile("qa_data/certs/sample_cert_a.cer")
if (success != True):
    print(cert.lastErrorText())
    sys.exit()

# Load the private key.
bd = chilkat.CkBinData()
success = bd.LoadFile("qa_data/certs/sample_key_a.key")
success = privKey.LoadAnyFormat(bd,"privateKeyPasswordIfNecessary")
if (success != True):
    print(privKey.lastErrorText())
    sys.exit()

# Associate the private key with the cert.
success = cert.SetPrivateKey(privKey)
if (success != True):
    print(cert.lastErrorText())
    sys.exit()

# Set the certificate to be used for mutual TLS authentication
# (i.e. sets the client-side certificate for two-way TLS authentication)
success = http.SetSslClientCert(cert)
if (success != True):
    print(http.lastErrorText())
    sys.exit()

# At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS
# connection will automatically use it if the server demands a client-side cert.
