I've been running Access Data Password Recovery Toolkit (PRTK) on a bunch of encrypted archives (all zip files, I think they were encrypted with 7Zip AES-256) for a while and haven't had any hits. I decided to test if PRTK is working at all and made a simple AES-256 encrypted zip file with 7Zip.
The password was 'password' and I made a dictionary consisting of only the word 'password'. I turned off all the other dictionaries and every rule except for the 'dictionary primaries' rule and the 'as is' rule.
Surely enough the crack finished in less than a second and said that it didn't find anything.
Any ideas why this is happening? I feel like I've probably wasted the last couple of weeks trying to crack files that PRTK can't even crack.
