(CkPython) Workaround for the deprecated Crypt2.OpaqueVerifyBytesENC method

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

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

import chilkat

crypt = chilkat.CkCrypt2()

crypt.put_EncodingMode("base64")

# ------------------------------------------------------------------------
# The OpaqueVerifyBytesENC method is deprecated:

outData = chilkat.CkByteData()

success = crypt.OpaqueVerifyBytesENC("base64 encoded p7m",outData)

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

bd = chilkat.CkBinData()
bd.AppendEncoded("base64 encoded p7m","base64")

# If the opaque signature is validated, the contents of bd are replaced with the original data that was signed.
# 
success = crypt.OpaqueVerifyBd(bd)
