WebMedieval Cryptography. It was probably religiously motivated textual analysis of the Qur'an which led to the invention of the frequency analysis technique for breaking monoalphabetic substitution ciphers, possibly by Al-Kindi, an Arab mathematician, sometime around AD 800 (Ibrahim Al-Kadi −1992). It was the most fundamental cryptanalytic ... WebFrequency analysis Human languages tend to use some letters more than others. For example, "E" is the most popular letter in the English language. We can analyze the frequency of the characters in the message and identify the most likely "E" and narrow down the possible shift amounts based on that. Try it out yourself!
