Note: This example requires Chilkat v11.0.0 or greater.

use chilkat();

$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);

$crypt->put_EncodingMode("base64");
$crypt->put_HashAlgorithm("sha256");

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

# ------------------------------------------------------------------------
# The SignBytesENC method is deprecated:

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

$base64_sig = $crypt->signBytesENC($inData);

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

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

$base64_sig = $crypt->signBdENC($bdIn);
