(PHP Extension) CAdES BES Detached Signature

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

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$crypt = new CkCrypt2();

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

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

// Tell the crypt component to use this cert.
$success = $crypt->SetSigningCert($cert);
if ($success != true) {
    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->put_CadesEnabled(true);

// 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 == false) {
    print $crypt->lastErrorText() . "\n";
    exit;
}

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

print 'Success!' . "\n";
