Crunch: powerpack <source> <destination> <-c> [-e=EFFICIENCY] [-p=PASSWORD] [-o] [-h]
Decrunch: powerpack <source> <destination> <-d> [-p=PASSWORD] [-h]
With:
-c: Crunch (compress)
-d: Decrunch (decompress)
EFFICIENCY: 1 = Fast, 2 = Mediocre, 3 = Good (def), 4 = Very Good, 5 = Best
PASSWORD: Encrypt/decrypt file. Max 16 characters
-o: Use it to compress with the old PP alorithm.
The difference in the size of a window:
- Old version: 0x4000
- New version: 0x8000
-h: Show this help
I've decompiled the original library and restored source code of the original compression algo (including the encryption).
