- NAME
- HackProPack 1.00a
-
- SYNOPSIS
- HackProPack FILE/A,FROM/K,TO/K
-
- DESCRIPTION
- The cruncher ProPack by Rob Northen Computing offers a
- special mode for crunching data files with a 16 bit key.
- This prevents unauthorized persons from unpacking such
- a file if they don't have the right key. Until yesterday!
-
- HackProPack finds the right keys for locked data files.
- It requires either Kickstart V37+ or the arp.library
- together with older OS releases.
-
- FILE specifies the file that should be analyzed.
- No wildcards supported.
-
- Usually the whole possible range of keys (1-65535/$1-$ffff)
- will be tested on the locked file. With FROM and TO, you
- may set a different range. This is useful if you want to
- have a guess first, or if you don't want to wait all the
- time to scan the whole range but do it step by step. Both
- FROM and TO support either decimal or hexadecimal values.
-
- When the right key has been found, write it down somewhere
- and decrunch the file either with ProPack or xfdDecrunch.
-
- EXAMPLES
- Shell> HackProPack DH0:Data/Locked.RNC
- Tests all possible keys on that file.
-
- Shell> HackProPack Locked.RNC FROM 4000 TO 5000
- Tests keys 4000 to 5000 on that file.
-
- Shell> HackProPack Locked.RNC TO $8000
- Tests keys $1 to $8000 on that file.
-
- ABOUT
- HackProPack uses a totally new method to find the right
- key. The file is unpacked only once, together with an
- array of key-related information. The actual key scanning
- is only based on that array and a 16 bit CRC checksum.
- Together with the highly optimized code, this certainly
- is the fastest method ever developped on the Amiga.
-
- BUT: You need CrunchedLength+(UncrunchedLength*2) bytes
- of free memory.
-
- The scanning time depends on the size of the data file,
- the key itself (1234 will be reached earlier than 5678)
- and certainly on your CPU speed. For really big files
- (256-512kB), it might take some hours.
-
