Software Compress
-
Version
1.2
Software Compress is designed for pack and protect
your EXE-files. Freeware Lite version compresses
approximately 50%, FULL version has more powerful
compression. Software Compress is the unique software
for pack and protect your executables. Protection
level is enough high to prevent disassembly and patch
of your software. So it reduces chances to see you
program being cracked and spreaded everywhere.
Executable file always contains superfluous code. It
allows compress exe-file up to 30-60% original.
However, there is not enough to pack exe-file to
archive. It must have an added loader-unpacker to run.
Unpacked piece of code loads packed code to memory, to
unpack and run it. We implemented this algorithm in
our software. Algorithm uses one-pass compression and
dictionary and provides highest compression level.
When packed program runs, it reads the dictionary and
unpacks code into RAM in one pass. The unpacking speed
is very fast (40 megabytes per second) because
compression takes some time (few seconds). So no
delays during execution of the packed program. Crack
and patch protection is provided by packing original
code. Altering packed code will result to broken
archive and impossible unpacking. Disassembly
protection bases on it too. Cracker would obtain only
source code of unpacker section and not original code.
