WELCOME
|
|
=======
|
|
|
|
Welcome to UPX !
|
|
|
|
Please don't forget to read the file LICENSE - UPX is distributed
|

under the GNU General Public License (GPL) with special exceptions
|

allowing the distribution of all compressed executables, including

commercial programs.

|
INTRODUCTION
|
|
============
|
|
|
|
UPX is an advanced executable file compressor. UPX will typically
|
|
reduce the file size of programs and DLLs by around 50%-70%, thus
|
|
reducing disk space, network load times, download times and
|
|
other distribution and storage costs.
|
|
|
|
Programs and libraries compressed by UPX are completely self-contained
|
|
and run exactly as before, with no runtime or memory penalty for most
|
|
of the supported formats.
|
|
|
|
UPX supports a number of different executable formats, including
|
|
Windows programs and DLLs, macOS apps and Linux executables.
|
|
|
|
UPX is free software distributed under the term of the GNU General
|
|
Public License. Full source code is available.
|
|
|
|
UPX may be distributed and used freely, even with commercial applications.
|
|
See the UPX License Agreement for details.

|
SECURITY CONTEXT
|
|
================
|
|
|
|
IMPORTANT NOTE: UPX inherits the security context of any files it handles.
|
|
|
|
This means that packing, unpacking, or even testing or listing a file requires
|
|
the same security considerations as actually executing the file.
|
|
|
|
Use UPX on trusted files only!
|
|
|
|
|
|
SHORT DOCUMENTATION
|
|
===================
|
|
|
|
'upx program.exe' will compress a program or DLL. For best compression
|
|
results try 'upx --best program.exe' or 'upx --brute program.exe'.
|
|
|
|
Please see the file UPX.DOC for the full documentation. The files
|
|
NEWS and BUGS also contain various tidbits of information.
|
|
|
|
|
|
THE FUTURE
|
|
==========
|
|
|
|
- Stay up-to-date with ongoing OS and executable format changes.
|
|
|
|
- RISC-V 64 for Linux.
|
|
|
|
- We will *NOT* add any sort of protection and/or encryption.
|
|
This only gives people a false feeling of security because
|
|
all "protectors" can be broken by definition.
|
|
|
|
- Fix all remaining bugs - please report any issues
