See more REST Examples

Demonstrates how to use a client certificate with a REST connection where the certificate and private key are located on a USB token or smart card.

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

# This example shows how to use the Chilkat socket object's connection.

# Set the certificate to be used for mutual TLS authentication
cert = chilkat2.Cert()

# If the smartcard or token requires a PIN...
