Amaliy qism:

1-rasmda ko’rsatilgandek shifrlovchi kodlarni yozdim.



2-rasmda shu shirlovchi kodlarni davomi.

3 – rasmda shu shirlovchi kodlarni davomi..


4-rasmda shifrimizni yakuni

Xulosa
Ma’lumotlarni shifrlash va deshifrlash dasturini ishlab chiqishda RC4 algoritmidan foydanlandim.
RC4 oqimli shifrlash algoritmining dasturiy ta’minotini yaratishda java dasturlash tilidan foydalandim bunda biz ochiqmatni va kalitni kiritamiz men yozgan dastur sizga siz kiritgan ochiqmatni boshida shirflab keying qatorga dishirflab chiqaradi mavzuga oid adabiyotlarni to’pladim va tahlil qildim. Android studio dasturida ma’lumotlarni shifrlash dasturini yaratishningning nazariy asоslari bilan tanishidim.
Mavzuga oid adabiyotlarni to’pladim va tahlil qildim. Android studio dasturida ma’lumotlarni shifrlash dasturini yaratishningning nazariy asоslari bilan tanishidim. Ma’lumotlarni shifrlash dasturini yaratishda foydalaniladigan dastur-larni tahlil qildim. Android studio dasturida ishlash ko’nikmalariga ega bo’ldim. Android studio dasturi interfeysi haqida ma’lumot to’pladim. Chunki shu yillarda butun dunyoda axborot eng katta kuchga aylangan. Bunda RC4 shifrlash algoritmidan foydalandim va bu eng yaxshi va xavfsizlik bo’yicha birinchi o’rinda turadi butun dunyoda. RC4 shifrlash algoritmida axborot 10 qadam orqali shifrlanadi va buni buzishning iloji yo’q. Men bu dastur yaratish mobaynida RC4 algoritmini mukammal o’rgandim, ma’lumotlarni shifrlash dasturini yaratishda va foydalanishda qo’lladim. Android studio dasturida ishlash ko’nikmalariga ega bo’ldim. Yaratilgan ma’lumotlarni shifrlash dasturida mahsulotidan foydalanish yo`riqnomasini ishlab chiqdim. Android studio dasturi interfeysi haqida ma’lumotlarni to’pladim. Ma’lumotlarni shifrlash axborot vositasi xavfsizligini tamirlash uchun avvalo ulardagi ma’lumotlarni shifrlash kerak o’zimiz uchun foydali. Ma’lumotlarni shifrlash dasturini yaratishda foydalaniladigan dasturlarni tahlil qildim. Android studio dasturida ishlash ko’nikmalariga ega bo’ldim. Android studio dasturi interfeysi haqida ma’lumot to’pladim. Chunki shu yillarda butun dunyoda axborot eng katta kuchga aylangan.
