(Perl) Workaround for the deprecated Crypt2.SignString method

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

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);

# Sign the utf-8 byte representation of the text.
$crypt->put_Charset("utf-8");

$textToSign = "This is the text to sign";

# ------------------------------------------------------------------------
# The SignString method is deprecated:

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

$success = $crypt->SignString($textToSign,$outData);

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

$crypt->put_EncodingMode("base64");
$base64_sig = $crypt->signStringENC($textToSign);

# If you want the binary bytes of the signature decoded from base64.
$bdSig = chilkat::CkBinData->new();
$bdSig->AppendEncoded($base64_sig,"base64");
