Set a TLS Client Certificate from a Cert Object

See more Socket/SSL/TLS Examples

Demonstrates Socket.SetSslClientCert, which configures a certificate as the client certificate for subsequent TLS connections. The certificate must have access to its private key.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

import sys
import chilkat

success = False

socket = chilkat.CkSocket()

#  The file path is relative to the application's current working directory.  An absolute path
#  may also be used.  Supply the path appropriate to your own environment.
#  The PFX password should come from a secure source rather than being hard-coded.
pfxPassword = "myPfxPassword"
cert = chilkat.CkCert()
success = cert.LoadPfxFile("qa_data/client.pfx",pfxPassword)
if (success == False):
    print(cert.lastErrorText())
    sys.exit()

#  Configure the client certificate before connecting.  Use this only when the server requests or
#  requires client-certificate authentication (mutual TLS).
success = socket.SetSslClientCert(cert)
if (success == False):
    print(socket.lastErrorText())
    sys.exit()

bTls = True
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
if (success == False):
    print(socket.lastErrorText())
    sys.exit()

print("Connected with mutual TLS.")
