Decrypting the APCO cipher without the key.
Decryption without the key is obviously a much more difficult
process. Indeed, the purpose of encryption is to make it as
difficult as possible for anyone who does not know the key to read
the plain text. We will be using an unsophisticated password
cracking technique called a brute force attack. A brute
force attack on the APCO cipher works by trying every possible four
digit key (from 0000 to 9999) and keeping...

Assignment 7: Caesar Cipher Assignment 7 You will create a Caesar cipher which allows the user to specify the key and the text to be encrypted. A Caesar cipher is a simple substitution cipher wherein each letter in the message is shifted a certain number of spaces down the alphabet -- this number is called the key. a b c d e f g h i j k l m n o p q r s t u v w...

3) (10 pts) For the purposes of this question, a permutation of size n is any ordering of the integers 0, 1, 2, ..., n-1. We define a spaced-out permutation of size n to be a permutation such that two consecutive terms in the permutation differ by at least 2. For example, [0, 2, 4, 1, 3] is a spaced out permutation of size 5, and [5, 2, 4, 0, 3, 1] is a spaced out permutation of size 6,...

Can i get Playfair Cipher for python 3 that encrypts a message and decrypts it, could you possibly make it as simple as you can without losing functionality. please include comments, that would help me better understand Example of PlayFair Cipher: https://en.wikipedia.org/wiki/Playfair_cipher The Playfair cipher uses a 5 by 5 table containing a key word or phrase. Memorization of the keyword and 4 simple rules was all that was required to create the 5 by 5 table and use the...
