(Ruby) 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.

sock = Chilkat::CkSocket.new()

# Set the certificate to be used for mutual TLS authentication
# (i.e. sets the client-side certificate for two-way TLS authentication)
success = sock.SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx","pfxPassword")
if (success != true)
    print sock.lastErrorText() + "\n";
    exit
end

# 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).
bTls = true
port = 443
maxWaitMs = 5000
success = sock.Connect("www.example.com",port,bTls,maxWaitMs)
if (success != true)
    print "Connect Failure Error Code: " + sock.get_ConnectFailReason().to_s() + "\n";
    print sock.lastErrorText() + "\n";
    exit
end

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