CAdES BES Detached Signature

See more Encryption Examples

Demonstrates how to create a CAdES BES detached signature file (.p7s). Perl

use chilkat();

$success = 0;

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

$crypt = chilkat::CkCrypt2->new();

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

$cert = chilkat::CkCert->new();
$success = $cert->LoadPfxFile($pfxPath,$pfxPassword);
if ($success != 1) {
    print $cert->lastErrorText() . "\r\n";
    exit;
}

# Tell the crypt component to use this cert.
$success = $crypt->SetSigningCert($cert);
if ($success != 1) {
    print $crypt->lastErrorText() . "\r\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->put_CadesEnabled(1);

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

# Create the detached CAdES-BES signature:
$success = $crypt->CreateP7S($inFile,$sigFile);
if ($success == 0) {
    print $crypt->lastErrorText() . "\r\n";
    exit;
}

$success = $crypt->VerifyP7S($inFile,$sigFile);
if ($success == 0) {
    print $crypt->lastErrorText() . "\r\n";
    exit;
}

print "Success!" . "\r\n";
