Workaround for the deprecated Crypt2.VerifyBytes method

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

import chilkat

crypt = chilkat.CkCrypt2()

sigPath = "c:/someDir/example.p7s"
originalDataPath = "c:/someDir/example.dat"

# ------------------------------------------------------------------------
# The VerifyBytes method is deprecated:

detachedSigBytes = chilkat.CkByteData()
detachedSigBytes.loadFile(sigPath)

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

verified = crypt.VerifyBytes(originalDataBytes,detachedSigBytes)

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

bdSig = chilkat.CkBinData()
bdSig.LoadFile(sigPath)

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

encoding = "base64"
crypt.put_EncodingMode(encoding)
verified = crypt.VerifyBdENC(bdOrigData,bdSig.getEncoded(encoding))
