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]

# 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.

# The contents of bd are replaced with the opaque signature.
