mPress-Compressor-GUI

MPRESS is a free, high-performance executable packer for PE32/PE32+/.NET/MAC-DARWIN executable formats!

MPRESS makes programs and libraries smaller, and decrease start time when the application loaded from a slow removable media or from the network. It uses in-place decompression technique, which allows to decompress the executable without memory overhead or other drawbacks; it also protects programs against reverse engineering by non-professional hackers. Programs compressed with MPRESS run exactly as before, with no runtime performance penalties. MPRESS is absolutely free of charge software. MPRESS uses own LZMAT - extremely fast data compression library. Version 2.00 of the MATCODE Compressor has been released on 21st March 2009, now MPRESS has an optional LZMA compression. in March 2011 Mr. DonDD has created and published his MPRESS GUI, see link below.

LZMAT

LZMAT is an extremely fast real-time lossless data compression library!

LZMAT library v1.0 is written for x86 and x64 (AMD64) architectures. LZMAT_GUI is a 32bit Windows application which uses LZMAT compression library and demonstrates the compression speed. This program can be used to compress some big files or directories (i.e. VM images, disc images, for backup of some important folders,...).

LZMAT Features:

• Very fast compression-decompression
• Does not require memory for decompression
• Supports overlapping compression and in-place decompression
• Thread safe algorithm
• Written in ANSI C
• Small decompression procedure
• LMAT algorithms and implementation are distributed under the terms of the GNU General Public License (GPL) . Special licenses for commercial and other applications are available by contacting the author.

Platforms: x86, x64(AMD64)

DumpHEX:

In computing, a hex dump is a textual hexadecimal view (on screen or paper) of computer data, from memory or from a computer file or storage device. Use of a hex dump of data is usually done in the context of either debugging, reverse engineering or digital forensics. Interactive editors that provide a similar view but also manipulating the data in question are called hex editors.

In a hex dump, each byte (8 bits) is represented as a two-digit hexadecimal number. Hex dumps are commonly organized into rows of 8 or 16 bytes, sometimes separated by whitespaces. Some hex dumps have the hexadecimal memory address at the beginning. On systems where the conventional representation of data is octal, the equivalent is an octal dump.

This dumpHEX is not an editor in the true sense and only features a search function for ASCII characters.

The leftmost column is the hexadecimal displacement (or address) for the values of the following columns. Each row displays 16 bytes, with the exception of the row containing a single *. The * is used to indicate multiple occurrences of the same display were omitted. The last line displays the number of bytes taken from the input.

An additional column shows the corresponding ASCII character translation with hexdump -C or hd:

This is helpful when trying to locate TAB characters in a file which is expected to use multiple spaces.
The -v option causes hexdump to display all data verbosely:
