Workaround for the deprecated Crypt2.OpaqueSignBytesENC method

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

load ./chilkat.dll

set success 0

set crypt [new_CkCrypt2]

set cert [new_CkCert]

# ...
# Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
# 
set success [CkCrypt2_SetSigningCert $crypt $cert]

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

# ------------------------------------------------------------------------
# The OpaqueSignBytesENC method is deprecated:

set inData [new_CkByteData]

CkByteData_loadFile $inData $path

CkCrypt2_put_EncodingMode $crypt "base64"
set base64_sig [CkCrypt2_opaqueSignBytesENC $crypt $inData]

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

set bd [new_CkBinData]

CkBinData_LoadFile $bd $path

# The contents of bd are replaced with the opaque signature.
set success [CkCrypt2_OpaqueSignBd $crypt $bd]

set base64_sig [CkBinData_getEncoded $bd "base64"]

delete_CkCrypt2 $crypt
delete_CkCert $cert
delete_CkByteData $inData
delete_CkBinData $bd
