Workaround for the deprecated Crypt2.VerifyString method

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

load ./chilkat.dll

set crypt [new_CkCrypt2]

# Specifies how the original data bytes are converted to characters
CkCrypt2_put_Charset $crypt "utf-8"

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

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

set detachedSigBytes [new_CkByteData]

CkByteData_loadFile $detachedSigBytes $sigPath

set verified [CkCrypt2_VerifyString $crypt $originalText $detachedSigBytes]

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

set bdSig [new_CkBinData]

CkBinData_LoadFile $bdSig $sigPath

set encoding "base64"
CkCrypt2_put_EncodingMode $crypt $encoding
set verified [CkCrypt2_VerifyStringENC $crypt $originalText [CkBinData_getEncoded $bdSig $encoding]]

delete_CkCrypt2 $crypt
delete_CkByteData $detachedSigBytes
delete_CkBinData $bdSig
