  Shifrlashning blokli algoritmi
  - shifrlash algoritmi bo‘lib,
  kalitning har bir muayyan qiymatida belgilangan uzunlikdagi ochiq
  matn bloklari to‘plami ustida bitta qaytariluvchi akslantirishni
  amalga oshiradi. Belgilangan uzunlikdagi matn bloklarini oddiy
  almashtirish algoritmi hisoblanadi.
  Block encryption algorithm
  - encryption algorithm that
  implements a fixed value for each key one reversible mapping of
  open block s of text with a fixed length. Algorithm is simple
  replacement of text blocks of fixed length.
