Axborot xavfsizligiga ma’lumotlarning xavfsizligi va maxfiyligini ta’minlash uchun shifrlash va deshifrlash algoritmlarini qo‘llash orqali erishish mumkin, ayniqsa ular xavfsiz bo‘lmagan aloqa kanali orqali uzatilganda. Shifrlash - bu ruxsatsiz kirishning oldini olish va
ma’lumotlarning yaxlitligi va maxfiyligini ta’minlash uchun axborotni kodlash usuli bo‘lib, teskari jarayon deshifrlash deb ataladi. Barcha shifrlash algoritmlari ma’lumotlarni xavfsiz saqlashga qaratilgan; ammo ularning samaradorligi fayl hajmi, turi, murakkabligi va ishlatiladigan platforma kabi bir qancha omillarga qarab o‘zgaradi. Bundan tashqari, ba’zi shifrlash algoritmlari boshqalaridan ustun bo‘lsa-da, ular ma’lum bir hujumlarga nisbatan zaif ekanligi isbotlangan. Ushbu maqolada biz keng tarqalgan shifrlash algoritmlarining umumiy ko‘rinishini taqdim etamiz va ularning ichki ishlashini tushuntiramiz.
