Decipher the following. They have been enciphered using a Shift Cipher with the given key.

OMFMOAYNE, key = 12.
TJNXWNVM, key = 19.
LHAXEWJ, key = 22.
DBSLEXO, key = 10.
GDBPC ATVXDC, key =15.

Decipher the following. They have been enciphered using a Shift Cipher with the given key.

QSBHIFWCB, key = O.
CQN ADKRLXW ARENA, key = J.
ZKBYQD SQBUDTQH, key = Q.
VTXLTKBTG LXVMBHG, key = T.

Expert Solution

In cipher encryption and decryption all the alphabets are in the number that matches its order in the alphabet starting from 0.

A=0, B=1, C=2, ... , Y=24, Z=25.

The formula to decrypt the cipher code is:

decrypt_alphabet = (encrypt_alphabet_number + key) mod 26

Step by step solution of all questions are in the below picture

So, the answer is:

1. OMFMOAYNE, key = 12.

CATACOMBS

2. TJNXWNVM, key = 19

AQUEDUCT

3. LHAXEWJ, key = 22.

PLEBIAN

4. DBSLEXO, key = 10.

TRIBUNE

5. GDBPC ATVXDC, key =15.

ROMAN LEGION

6. QSBHIFWCB, key = O.

CENTURION

7. CQN ADKRLXW ARENA, key = J.

THE RUBICON RIVER

8. ZKBYQD SQBUDTQH, key = Q.

JULIAN CALENDAR

9. VTXLTKBTG LXVMBHG, key = T.

Write a Java program to encrypt the following message using the RC4 cipher using key CODES:...

Write a Java program to encrypt the following message using the RC4 cipher using key CODES: Cryptography is a method of protecting information and communications through the use of codes so that only those for whom the information is intended can read and process it. Instead of using stream length 256, we will use length 26. When encrypting, let A = 0 to Z = 25 (hence CODES = [2 14 3 4 18]). Ignore spaces and punctuations and put...

In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. Given an arbitrary cipher text file, you need to write a C++ program to find out the value of the shift going down the...

A Caesar cipher encrypts a message by shifting letters in the alphabet. For example, a shift of 4 maps 'a' to 'e' and maps 'p' to 't' Here is a famous line from Shakespeare encrypted with a shift of 4: 'vq dg qt pqv vq dg: vjcv ku vjg swguvkqp.' (a) Write a program that takes as input a string to be encrypted and an integer encrpytion shift (such as 4 mentioned earlier), and prints the encrypted string. [Hint: zip()...
