CAdES BES Detached Signature

See more Encryption Examples

Demonstrates how to create a CAdES BES detached signature file (.p7s). Chilkat2 PHP

<?php

use Chilkat2\Cert;
use Chilkat2\Crypt2;

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

$crypt = new Crypt2();

// 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 Cert();
try {
    $cert->LoadPfxFile($pfxPath, $pfxPassword);

    // Tell the crypt component to use this cert.
    $crypt->SetSigningCert($cert);

    // 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 = 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:
    $crypt->CreateP7S($inFile, $sigFile);

    $crypt->VerifyP7S($inFile, $sigFile);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo "Success!\n";
