Perl Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.OpaqueSignBytes method

Shows how to replace the deprecated OpaqueSignBytes 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 OpaqueSignBytes method is deprecated:

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

$outData = chilkat::CkByteData->new();

$success = $crypt->OpaqueSignBytes($inData,$outData);

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

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

#  If successful, the contents of bd are replaced with the PKCS#7 signed-data.
$success = $crypt->OpaqueSignBd($bd);
