Construct a Playfair matrix with the key RHYME Use the playfair matrix you just constructed and decrypt the following message: "PEYFQUGVHSMFPURHPERESUTG". Make sure you use your knowledge of the plaintext language and decide whether to use I or J in the decrypted message. Remove all filler letters, separate out the words when writing the final answer. Note: Place I and J in the same cell and assume filler letter is X.

Hello! I'm trying to write a code that will either encrypt/decrypt a message from an inputed text. I'm having the absolute hardest time getting stared and figuring out how to identify in the code if the input needs to be encrypted/decrypted and identifying the string to encrypt/decrypt with. These are the instructions: Objectives Command line input File input and output Rethrowing exceptions Program Description Gaius Julius Caesar encoded his battle messages so that the opponent could not read them should...

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...
