What is hachoir
hachoir is:
Hachoir is a Python library used to represent of a binary file as a tree of Python objects. Each object has a type, a value, an address, etc. The goal is to be able to know the meaning of each bit in a file.
Why using slow Python code instead of fast hardcoded C code? Hachoir has many interesting features:
- Autofix: Hachoir is able to open invalid / truncated files
- Lazy: Open a file is very fast since no information is read from file, data are read and/or computed when the user ask for it
- Types: Hachoir has many predefined field types (integer, bit, string, etc.) and supports string with charset (ISO-8859-1, UTF-8, UTF-16, …)
- Addresses and sizes are stored in bit, so flags are stored as classic fields
- Endian: You have to set endian once, and then number are converted in the right endian
- Editor: Using Hachoir representation of data, you can edit, insert, remove data and then save in a new file.
Hachoir provides command-line tools using its parsers:
- hachoir-grep: find a text pattern in a binary file
- hachoir-metadata: get metadata from binary files
- hachoir-strip: modify a file to remove metadata
- hachoir-urwid: display the content of a binary file in text mode
- hachoir-wx: display the content of a binary file in a GUI
