Workaround for the deprecated Crypt2.OpaqueSignBytesENC method

Shows how to replace the deprecated OpaqueSignBytesENC method. (Chilkat is moving away from the use of CkByteData.) Perl

use chilkat();

$success = 0;

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

$cert = chilkat::CkCert->new();
# ...
# Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
# 
$success = $crypt->SetSigningCert($cert);

$path = "c:/someDir/example.dat";

# ------------------------------------------------------------------------
# The OpaqueSignBytesENC method is deprecated:

$inData = chilkat::CkByteData->new();
$inData->loadFile($path);

$crypt->put_EncodingMode("base64");
$base64_sig = $crypt->opaqueSignBytesENC($inData);

# ------------------------------------------------------------------------
# Workaround.
# (Chilkat is moving away from using CkByteData)

$bd = chilkat::CkBinData->new();
$bd->LoadFile($path);

# The contents of bd are replaced with the opaque signature.
$success = $crypt->OpaqueSignBd($bd);

$base64_sig = $bd->getEncoded("base64");
