(PHP ActiveX) CAdES BES Detached Signature

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

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
$crypt = new COM("Chilkat.Crypt2");

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Cert')
$cert = new COM("Chilkat.Cert");
$success = $cert->LoadPfxFile($pfxPath,$pfxPassword);
if ($success != 1) {
    print $cert->LastErrorText . "\n";
    exit;
}

// Tell the crypt component to use this cert.
$success = $crypt->SetSigningCert($cert);
if ($success != 1) {
    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:
$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 . "\n";
    exit;
}

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

print 'Success!' . "\n";
