No hash-mode matches the structure of the input hash (pkzip2) - darkside - 12-30-2025
I have zip compressed file.
It contains 2 files. One relatively small PDF, and one big file (about 3 GB)
I tried to extract hash with zip2hashcat and zip2john (and adjust for hashcat)
In both cases I get "No hash-mode matches the structure of the input hash" information.
Hash from PDF file is about 2MB size and from the big file the hash size is about 5GB so more than the archive itself.
I tried with 'checksum only' hash and indeed it works in hashcat but I get a lot false positive results.
I don't want to use john because I can't get my GPU to work with it (compiled jumbo version).
Do I miss something?
