Question

The Caesar Cipher has 25 different shifts to try. How many possibilities are there to try in a random substitution cipher

Answer 1

Answer: 26! or
`\approx 4.03*10^(26)`

Explanation:

• The Caesar Cipher is an encoding method that shifts alphabets.
• The random substitution is an encoding method that move each letter of the alphabet randomly to different .

Given : The Caesar Cipher has 25 different shifts to try.

Since the total a letters in the English Alphabet = 26

Then, the number of possibilities in a random substitution cipher =
`26!`

`=26*25*24*23*...*3*2*1\\\\=4.03*10^(26)`

Hence, there are 26! ( or
`\approx 4.03*10^(26)`) possibilities to try in a random substitution cipher .
