Use Installed Cert on Windows for TLS Client Authentication

See more HTTP Examples

Demonstrates how to use a certificate that has already been installed on a Windows PC for TLS client authentication. Chilkat2 Perl

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

my $http = Chilkat2::Http->new;

# On Windows, a pre-installed certificate can be loaded in a number of different ways.
# This example loads by the common name:
my $cert = Chilkat2::Cert->new;
my $success = $cert->LoadByCommonName('My ECA Medium Assurance Identity Certificate');
if (!$success) {
    print $cert->LastErrorText, "\n";
    exit;
}

# Make sure this certificate has a private key available.
# It should be a private key such that when the certificate was installed, it was marked as "exportable"
# so that authorized programs are able to access the private key.
if (!$cert->HasPrivateKey()) {
    print "A private key is needed for TLS client authentication.\n";
    print "This certificate has no private key.\n";
    exit;
}

# Set the certificate to be used for mutual TLS authentication
# (i.e. sets the client-side certificate for two-way TLS authentication)
$success = $http->SetSslClientCert($cert);
if (!$success) {
    print $http->LastErrorText, "\n";
    exit;
}

# At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS
# connection will automatically use it if the server demands a client-side cert.
