EnScript to Compare evidence against hash set(s) and export files not in the hash set(s)

On an idea from Timothy LaTulippe, this EnScript was written to basically "de-NIST" your evidence.

This EnScript will compare all the files in the case against whatever hash sets you select (aka all the NIST ones or your own custom Windows hash sets) and then it will export all the files that do not match any of the hash sets, maintaining the original paths.

First, select whatever hash sets you want to use and rebuild your library with the ones you want to include in the comparison:

Then run the EnScript and choose an export path:

If you check the LEF box, a logical evidence file will also be made with all the files that do not match any of your included hash sets.

Check your export path for your case, it must be a valid path.

better late than never, but it appears you get that error if you have multiple instances on EnCase open, as the first instance of encase locks the encase.HASH file in \Program Files\EnCase.
