Perl

Create .p7s Compliant with ICP-Brazil Digital Signature Standard

See more CAdES Examples

Demonstrates how to create a .p7s signature that contains a data file, which in this case is a PDF. The .p7s will be compliant with the ICP-Brazil Digital Signature Standard.

Important: This example requires Chilkat v9.5.0.92 or later.

Perl

use chilkat();

$success = 0;

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

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

# Any type of file can be signed.  It doesn't have to be a PDF.
$inFile = "qa_data/pdf/helloWorld.pdf";

$bd = chilkat::CkBinData->new();
$success = $bd->LoadFile($inFile);
if ($success == 0) {
    print "Failed to load " . $inFile . "\r\n";
    exit;
}

# Get the certificate we'll be using to sign.
$cert = chilkat::CkCert->new();

$success = $cert->LoadPfxFile("qa_data/pfx/cert_test123.pfx","test123");
if ($success == 0) {
    print $cert->lastErrorText() . "\r\n";
    exit;
}

$success = $crypt->SetSigningCert($cert);
if ($success == 0) {
    print $crypt->lastErrorText() . "\r\n";
    exit;
}

# Set properties for signing...
$crypt->put_HashAlgorithm("sha256");

$jsonSigningAttrs = chilkat::CkJsonObject->new();
$jsonSigningAttrs->UpdateInt("contentType",1);
$jsonSigningAttrs->UpdateInt("signingTime",1);
$jsonSigningAttrs->UpdateInt("messageDigest",1);
$jsonSigningAttrs->UpdateInt("signingCertificateV2",1);

# Listed here are the currently existing profiles. (Chilkat will add additional ICP Brasil policy profiles in future versions as new ones are created.)
