I have a zip file,
Example.zip consisting of a directory
Example and three files *.dat. I can see the names of all 3 files. The dat files are encrypted (ZipCrypto Deflate). I’m interested to know if I can use bkcrack, and am aware of the required:
at least 12 bytes of contiguous plaintext.
My system has a modern 6c/12t CPU, and an older GPU.
- Can I use anything about the directory or filenames themselves for the required plaintext?
- If 1 is not possible what hints/course of action can I take to derive the 12 (or more) bytes.
I just need the files.
