(CkPython) Workaround for the deprecated Crypt2.VerifyBytesENC method

Shows how to replace the deprecated VerifyBytesENC 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()

# Encoding mode property must match the encoding of the detached signature.
crypt.put_EncodingMode("base64")

originalDataPath = "c:/someDir/example.dat"
base64_detached_signature = "...."

# ------------------------------------------------------------------------
# The VerifyBytesENC method is deprecated:

originalDataBytes = chilkat.CkByteData()
originalDataBytes.loadFile(originalDataPath)

verified = crypt.VerifyBytesENC(originalDataBytes,base64_detached_signature)

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

bdOrigData = chilkat.CkBinData()
bdOrigData.LoadFile(originalDataPath)

verified = crypt.VerifyBdENC(bdOrigData,base64_detached_signature)
