CAdES BES Detached Signature

See more Encryption Examples

Demonstrates how to create a CAdES BES detached signature file (.p7s). 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 $crypt = Chilkat2::Crypt2->new;

# Use a digital certificate and private key from a PFX file (.pfx or .p12).
my $pfxPath = '/Users/chilkat/testData/pfx/acme.pfx';
my $pfxPassword = 'test123';

my $cert = Chilkat2::Cert->new;
my $success = $cert->LoadPfxFile($pfxPath, $pfxPassword);
if (!$success) {
    print $cert->LastErrorText, "\n";
    exit;
}

# Tell the crypt component to use this cert.
$success = $crypt->SetSigningCert($cert);
if (!$success) {
    print $crypt->LastErrorText, "\n";
    exit;
}

# The CadesEnabled property applies to all methods that create PKCS7 signatures.
# To create a CAdES-BES signature, set this property equal to true.
$crypt->CadesEnabled(1);

# We can sign any type of file, creating a .p7s as output:
my $inFile = '/Users/chilkat/testData/pdf/sample.pdf';
my $sigFile = '/Users/chilkat/testData/p7s/sample.p7s';

# Create the detached CAdES-BES signature:
$success = $crypt->CreateP7S($inFile, $sigFile);
if (!$success) {
    print $crypt->LastErrorText, "\n";
    exit;
}

$success = $crypt->VerifyP7S($inFile, $sigFile);
if (!$success) {
    print $crypt->LastErrorText, "\n";
    exit;
}

print "Success!\n";
