Since Ibn Dunaynir was always in trouble and Ibn Durayhim had time, money, and a passion for encryption, they established the most important principle in modern encryption 800 years ago:
- Take a cleartext message
- Transform the letters into digits
- Apply mathematical operations on those digits
- Transform the digits back to letters to get the ciphertext
15. Ali Bin Adlan Al-Nahawi, for example, developed an encryption method based on substitution. In this method, the order of the Arabic alphabet is shuffled, and the key or the determined order is exchanged beforehand using a poem that contains all the alphabets in its verses. An example of such a verse is:
صحَّ عندي وقتُ شغل بهمُ أخذُ فظِّ كثُّ زطِّ ضَد جَسِ
1. Since the invention of writing, there have always been people who have sought to send secret messages, either for the purpose of conveying sensitive information or simply out of a desire for intrigue.
