CkPython Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.OpaqueVerifyString method

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

import chilkat

success = False

crypt = chilkat.CkCrypt2()

#  Specifies how the original data bytes are converted to characters
crypt.put_Charset("utf-8")

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

#  ------------------------------------------------------------------------
#  The OpaqueVerifyString method is deprecated:

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

originalText = crypt.opaqueVerifyString(inData)

#  ------------------------------------------------------------------------
#  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)

#  Indicate how the bytes are converted to chars by passing the charset.
originalText = bd.getString("utf-8")
