  Encryption with symmetric-key algorithm Kirmah.

  three modes are available to encrypt :

    - compression (full / disabled or only final step)
    - random (simulate a random order - based on crypted key - to randomize data)
    - mix (mix data according to a generated map - based on crypted key - with addition of noise)


  Process is as follow :

  for encryption :
    file > [ compression > ] encryption > [randomiz data > mix data > compression > ] file.kmh

    default options depends on file type (binary or text).
      - binary files are compressed only at the end of process
      - text files have a full compression mode
      - random and mix modes are enabled on all files

  for decryption :
    file.kmh > [ uncompression > unmix data > unrandomiz data] > decryption > [uncompression > ] file


  multiprocessing is avalaible for reducing encryption/decryption time.


  for encrypt large binary files, a fastest alternative is possible :
  the split command.

  the split command consist on splitting file into severals parts (with noise addition) according to
  a generated map based on the crypted key.
  the map is fully encrypted as a configuration file (.kcf) which is required to merge all parts

  the merge command is the opposite process.
