Workaround for the deprecated Crypt2.OpaqueSignString method

Shows how to replace the deprecated OpaqueSignString 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)

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

textToSign = "This is the text to sign"

# ------------------------------------------------------------------------
# The OpaqueSignString method is deprecated:

outData = chilkat.CkByteData()

success = crypt.OpaqueSignString(textToSign,outData)

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

crypt.put_EncodingMode("base64")
base64_sig = crypt.opaqueSignStringENC(textToSign)

bd = chilkat.CkBinData()
bd.AppendEncoded(base64_sig,"base64")

# Access the raw bytes from bd.
