H4z0t

The encoder project named by me is created for studying basics of information theory and encoding. The executable is a program for compressing, error-detection/correction and encryption of data.

Format structure

Format Header

Data: 4z0t format version data type files count Total
Bytes: 4 4 4 4 16

Format Data

After header files' data is written in this format:

File Header

Data: data size file name size compression type encryption type protection type additional data Total
Bytes: 8 4 4 4 4 8 32

File Data

After file header filename is written with its relative path in folder being encoded. Depending on the compression type, encryption type and protection type file's data is written.

Flags and Arguments

There are 3 arguments and 3 flags defined right now:

  • --decode and --encode are arguments for defining path(s) for file(s) to be processed
  • --into is argument for path where to store encoded/decoded data
  • -lz77 and -shanon-fano are flags for compression types
  • -hamming is flag for protection type
