Assalamu'alaikum warahmatullah wabarakatuh
Halo apa kabar? Semoga sehat selalu ya, hari ini aku akan berbagi ilmu dengan kalian seputar Keamanan Sistem Komputer mengenai Kriptografi Klasik
Kriptografi
Klasik sebagaimana materi tugas yang sudah diberikan sebelumnya, kali ini kita akan membahas
lebih mendalam berupa
BAGAIMANA CARA BEKERJAdari
kriptografi kalsik KRIPTOGRAFI KLASIKCAESAR CIPHER 1.CAESAR CIPHER 1adalah algoritma dimana tiap huruf alfabet= n + pesan
1.CAESAR CIPHER 1,
berdasarkan penjelasan contoh dari cara kerja
Algoritma Kriptografi Klasik CAESAR CIPHER 1, sebagai berikut:
a. Lakukan transformasi +5
b. Pesan yang ditransformasi “KEAMANAN SISTEM”
