(Tcl) Socket TLS Mutual Authentication (Client-Side Certificate)

This example demonstrates how to provide a client-side certificate, also known as "two-way authentication" or "mutual authentication" for servers that require a client certificate.

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

set sock [new_CkSocket]

# Set the certificate to be used for mutual TLS authentication
# (i.e. sets the client-side certificate for two-way TLS authentication)
set success [CkSocket_SetSslClientCertPfx $sock "/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx" "pfxPassword"]
if {$success != 1} then {
    puts [CkSocket_lastErrorText $sock]
    delete_CkSocket $sock
    exit
}

# 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.)

# Establish the connection using the socket object (with client certificate authentication).
set bTls 1
set port 443
set maxWaitMs 5000
set success [CkSocket_Connect $sock "www.example.com" $port $bTls $maxWaitMs]
if {$success != 1} then {
    puts "Connect Failure Error Code: [CkSocket_get_ConnectFailReason $sock]"
    puts [CkSocket_lastErrorText $sock]
    delete_CkSocket $sock
    exit
}

# At this point, the Socket object is connected and authenticated using the client-side cert

# ...

delete_CkSocket $sock
