The header in base64 is (or at leas to a multiple of 4 characters) is “UEsDBBQACAAIAKyEATkAAAAAAAAAAAAAAAAUAAAA”. I guess the beginning is probably a CDFILEHEADER struct (based on prior help) but I’m unable to decode it… 😦
The struct should start with a DSIG struct (16 bit unsigned integer and a 32 bit unsigned integer) but I’m unable to get anything that makes sense. I end up with 20555 for the first WORD but that doesn’t “compute”. Bummer!
If you’ve done any work on this and is willing to share please drop me a comment. Thanks.
