CkPython Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.OpaqueVerifyBytes method

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

import chilkat

success = False

crypt = chilkat.CkCrypt2()

path = "c:/someDir/example.p7m"

#  ------------------------------------------------------------------------
#  The OpaqueVerifyBytes method is deprecated:

inData = chilkat.CkByteData()
inData.loadFile(path)

outData = chilkat.CkByteData()

success = crypt.OpaqueVerifyBytes(inData,outData)

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

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

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