Workaround for the deprecated Crypt2.SignBytesENC method

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

import chilkat

success = False

crypt = chilkat.CkCrypt2()

cert = chilkat.CkCert()
# ...
# 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()
inData.loadFile(path)

base64_sig = crypt.signBytesENC(inData)

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

bdIn = chilkat.CkBinData()
bdIn.LoadFile(path)

base64_sig = crypt.signBdENC(bdIn)
