CkPython Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.VerifyString method

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

import chilkat

crypt = chilkat.CkCrypt2()

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

originalText = "this is the string that was signed."
sigPath = "c:/someDir/example.p7s"

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

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

verified = crypt.VerifyString(originalText,detachedSigBytes)

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

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

encoding = "base64"
crypt.put_EncodingMode(encoding)
verified = crypt.VerifyStringENC(originalText,bdSig.getEncoded(encoding))
