Hachoir project- hachoir core
Hachoir is the french name for a mincer: a tool used by butchers to cut meat. Hachoir is also a tool written for hackers to cut a file or any binary stream. A file is split in a tree of fields where the smallest field can be just a bit. There are various field types: integer, string, bits, padding, sub file, etc. 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.
