set socket [new_CkSocket]

# Set the certificate to be used for mutual TLS authentication
# (i.e. sets the client-side certificate for two-way TLS authentication)
# Note: There are other ways to set the client certificate using Chilkat.
# For example, on Windows systems, a Chilkat certificate object could be loaded with certificate
# pre-installed (with private key) in a Windows certificate store, and then socket.SetSslClientCert could be called.

# Note: The certificate used for the client-side of TLS mutual authentication
# must have the associated private key available. (.pfx/.p12 files typically store both
# the certificate and associated private key.)
