Socket TLS Mutual Authentication (Client-Side Certificate)

See more Socket/SSL/TLS Examples

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. Chilkat2 Perl

use strict;
use warnings;
use Chilkat2;

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

my $sock = Chilkat2::Socket->new;

# Set the certificate to be used for mutual TLS authentication
# (i.e. sets the client-side certificate for two-way TLS authentication)
my $success = $sock->SetSslClientCertPfx('/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx', 'pfxPassword');
if (!$success) {
    print $sock->LastErrorText, "\n";
    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).
my $bTls = 1;
my $port = 443;
my $maxWaitMs = 5000;
$success = $sock->Connect('www.example.com', $port, $bTls, $maxWaitMs);
if (!$success) {
    print 'Connect Failure Error Code: ', $sock->ConnectFailReason, "\n";
    print $sock->LastErrorText, "\n";
    exit;
}

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