Update: hex-to-bin.py Version 0.0.5

Filed under: My Software,Update — Didier Stevens @ 0:00

This new version of hex-to-bin.py, a tool to convert hexadecimal data to binary data, has a new option to ignore al characters/bytes that are not hexadecimal digits: -H –hexonly.

This option can be used to parse obfuscated, hexadecimal dumps of PE files, for example:

And there are also options if you want to take only lowercase hexadecimal digits into account (–loweronly) or uppercase hexadecimal digits (–upperonly).

Update: hex-to-bin.py Version 0.0.4

Filed under: My Software,Update — Didier Stevens @ 0:00

This version of hex-to-bin.py, a simple tool to convert hexadecimal data to binary, can also handle bitstreams (option -b) with this update. If necessary, the bitstream is right-padded with 0s to make the bitstream length a multiple of 8.

Example:

Update: hex-to-bin.py Version 0.0.3

Filed under: My Software,Update — Didier Stevens @ 11:04

hex-to-bin.py is a program to convert hexadecimal dumps (text) to binary data.

This new version of hex-to-bin.py can handle different hexdump formats, like registry dumps (text files). Use option -x to handle these hexdumps.

And option -t was added if the input is a text file that is non-ASCII, like UTF16. Option -t can be used to convert the text file.

And it supports Python3, but that code is a kludge. Something I’ll have to do better later.

Update: hex-to-bin.py Version 0.0.2

Filed under: My Software,Update — Didier Stevens @ 10:47

This new version comes with option -a to parse ASCII/hexdumps as produced by my tools.

Option -s can be used to select another hexadecimal/ASCII dump than the first one (for example, -s 2 to select the second dump).

Option -l (list) can be used to produce an overview of all hexadecimal/ASCII dumps found in the input, together with an index number to be used with option -s.
