One failing of an encryption system occurs if a letter (or number) always encodes to the same value. Let’s see how we can exploit this weakness. Let’s assume that we know that the word GOOD is in this intercepted message: XLI3KSSH3HSGXIVD.
What are the encrypted values (i.e., give the mappings) of the letters G, O, D (i.e., G -> ?, O -> ?, and D -> ?) and what is the encryption algorithm?
To test your detective skills, what is the exact original message? (It’s a simple cipher where a letter or number always encodes to the same value). Hint: you need to find where GOOD would appear in the encrypted message.

**DO IT AS PYTHON PLEASE**
The Trifid Cipher General Problem Description The Trifid cipher (not to be confused with the creatures from the classic science-fiction film "The Day of the Triffids") is an algorithm that enciphers a plaintext message by encoding each letter as a three-digit number and then breaking up and rearranging the digits from each letter's encoded form. For this assignment, you will create a set of Python functions that can encode messages using this cipher (these functions...

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...

Project 6, Program Design One way to encrypt a message is to use a date’s 6 digits to shift the letters. For example, if a date is picked as December 18, 1946, then the 6 digits are 121846. Assume the dates are in the 20th century. To encrypt a message, you will shift each letter of the message by the number of spaces indicated by the corresponding digit. For example, to encrypt...

Part 3: Transposition Ciphers #can't use ord or chr functions You must implement three transposition ciphers (the "backwards" cipher, the Rail Fence cipher, and the Column Transposition cipher) where the ciphertext is created via an altered presentation of the plaintext. The algorithm for each is detailed in the function descriptions in this section. (13 points) def backwards_cipher(plaintext, key): • Parameter(s): plaintext ----- a string; the message to be encrypted key ----- an integer; the number to control this cipher •...

You will be writing a simple Java program that implements an ancient form of encryption known as a substitution cipher or a Caesar cipher (after Julius Caesar, who reportedly used it to send messages to his armies) or a shift cipher. In a Caesar cipher, the letters in a message are replaced by the letters of a "shifted" alphabet. So for example if we had a shift of 3 we might have the following replacements: Original alphabet: A B C...

Develop a Java application that uses a type of encrypted alphabet, called a random monoalphabetic cipher, to encrypt and decrypt a message. Your encryption key and message are to be read in from two different files and then the encrypted message will be output to third file. Then the encrypted message is read in and decrypted to a fourth file. A monoalphabetic cipher starts with an encryption word, removes the redundant letters from the word, and assigns what’s left to...
