UPX is a versatile executable packer with the following features:

excellent compression ratio: typically compresses better than WinZip/zip/gzip, use UPX to decrease the size of your distribution !


very fast decompression: ~10 MB/sec on an ancient Pentium 133, ~200 MB/sec on an Athlon XP 2000+.


no memory overhead for your compressed executables because of in-place decompression.


safe: you can list, test and unpack your executables. Also, a checksum of both the compressed and uncompressed file is maintained internally.


universal: UPX can pack a number of executable formats:
atari/tos
djgpp2/coff
dos/com
dos/exe
dos/sys
linux/386
rtm32/pe
tmt/adam
watcom/le (supporting DOS4G, PMODE/W, DOS32a and CauseWay)
win32/pe


portable: UPX is written in portable endian-neutral C++


extendable: because of the class layout it's very easy to add new executable formats or new compression algorithms


free: UPX is distributed with full source code under the GNU General Public License, and may be used freely even with commercial programs.
You probably understand now why we call UPX the "Ultimate Packer for eXecutables".

UPX is based on experience with our previous packers DJP and lzop and uses the NRV compression library.

Supported executable formats

Here is a detailed list of all supported executable formats:

UPX Pack Unpack Description Link
atari/tos X X Atari TOS/MiNT executable FreeMiNT portal
djgpp2/coff X X DOS 32-bit COFF djgpp homepage
dos/com X X DOS 16-bit .com file
dos/exe X X DOS 16-bit executable
dos/sys X X DOS 16-bit .sys file
linux/386 X X Linux AOUT/ELF/script Linux
rtm32/pe X X Windows 32-bit executable or DLL
tmt/adam X X DOS 32-bit executable TMT Pascal
watcom/le X X DOS 32-bit linear executable Watcom C/C++
win32/pe X X Windows 32-bit executable or DLL

SPECIAL EXCEPTION FOR COMPRESSED EXECUTABLES
============================================

The stub which is imbedded in each UPX compressed program is part
of UPX and UCL, and contains code that is under our copyright. The
terms of the GNU General Public License still apply as compressing
a program is a special form of linking with our stub.

Hereby Markus F.X.J. Oberhumer and Laszlo Molnar grant you special
permission to freely use and distribute all UPX compressed programs
(including commercial ones), subject to the following restrictions:

1. You must compress your program with a completely unmodified UPX
version; either with our precompiled version, or (at your option)
with a self compiled version of the unmodified UPX sources as
distributed by us.
2. This also implies that the UPX stub must be completely unmodfied, i.e.
the stub imbedded in your compressed program must be byte-identical
to the stub that is produced by the official unmodified UPX version.
3. The decompressor and any other code from the stub must exclusively get
used by the unmodified UPX stub for decompressing your program at
program startup. No portion of the stub may get read, copied,
called or otherwise get used or accessed by your program.


ANNOTATIONS
===========

- You can use a modified UPX version or modified UPX stub only for
programs that are compatible with the GNU General Public License.

- We grant you special permission to freely use and distribute all UPX
compressed programs. But any modification of the UPX stub (such as,
but not limited to, removing our copyright string or making your
program non-decompressible) will immediately revoke your right to
use and distribute a UPX compressed program.

- UPX is not a software protection tool; by requiring that you use
the unmodified UPX version for your proprietary programs we
make sure that any user can decompress your program. This protects
both you and your users as nobody can hide malicious code -
any program that cannot be decompressed is highly suspicious
by definition.

- You can integrate all or part of UPX and UCL into projects that
are compatible with the GNU GPL, but obviously you cannot grant
any special exceptions beyond the GPL for our code in your project.

- We want to actively support manufacturers of virus scanners and
similar security software. Please contact us if you would like to
incorporate parts of UPX or UCL into such a product.

thanks this tool rocks
can someone explain to me whats a "stub" and how should one use \ create one .

thanks again

Hello M8's

Thank You For The Reply Flame But What I Think A Stub Is This Below.>

I agree with what Scooby Is Relateing too, But I have found some more info below.

stub

A stub is a small program routine that substitutes for a longer program, possibly to be loaded later or that is located remotely.

For example, a program that uses Remote Procedure Calls (RPC) is compiled with stubs that substitute for the program that provides a requested procedure.

The stub accepts the request and then forwards it (through another program) to the remote procedure.

When that procedure has completed its service, it returns the results or other status to the stub which passes it back to the program that made the request.

1. <programming> A dummy procedure used when linking a program with a run-time library. The stub routine need not contain any code and is only present to prevent "undefined label" errors at link time.

2. <programming, networking> A local procedure in a remote procedure call. The client calls the stub to perform some task and need not necessarily be aware that RPC is involved. The stub transmits parameters over the network to the server and returns the results to the caller.

Abstract: USC is a new stub compiler which can be used to generate stubs which perform a wide variety of data conversion operations.

USC is flexible and can be used in situations were previously only manually code generation was possible. USC generated code is up to 20 times faster than code generated by traditional argument marshaling schemes such as ASN.1 and Sun XDR.

This paper presents the design of USC and a comprehensive set of experiments designed to compare USC performance with the best manually

What is stub.exe?
stub.exe is a small real-mode program which coff2exe attaches to the COFF executable code produced by djgpp. When you invoke a program compiled with djgpp, stub.exe is initially run.

It simply calls go32.exe, and passes it information it needs to run the COFF file attached to it. stub is much smaller than go32, so less disk space is used. Also, if you change go32, you don't have to change stub, and all the stub-ized programs will use the new go32 automatically.

Custom DOS Stub EXEs - VB automatically creates a DOS stub EXE for you when you build an executable.

The purpose for this is to output some text to the command line when your EXE is run from the DOS environment, explaining that it is a Windows app.

The Custom DOS Stub EXE feature allows you to place your own DOS stub EXE into your app, allowing you to customize the text that is displayed or even to run an actual DOS version of your application.

Also Flame maybe this might help too m8 this link below for more information

Oh Ok, I found 1 more thing this might help too

http://www.undu.com/Articles/010119d.html

And the last 1 here

http://dos32a.sourceforge.net/html/util/1.html

And Here Is The Very Last 1 And It Releast To RPC DCOM

This is all I can think of "Flame"
I Hope This Helps You And "Merry Christmas"

If I find anything else on STUBS I will post it

Yeah i know UPX rocks and its free
Enjoy it, it is very usefull !
They are so many GUI possible for UPX

may sound dumb, but can it be used to compress regular windows folders and stuff like that?

nope just.. exe file AFAIK used several times....very good

very tanks DJVASTVASTY2K !
this packer is very good but you know there are some other tools to do this .
i always use pecompact V1.84 very powerful but it is commercial .
-----------------------------------------------
happy new year , all GSO members

nice UPX roX da house. It`s very usefall 100000 thanks

tanks for tool
