If the last letter of the alphabet (letter '2') is reached, the program continues to count from the beginning of the alphabet (letter 'a'), The user enters the text and the encryption number (n), and the program prints the encrypted text. The program can be used to decrypt an encrypted text by entering the encrypted text and the negative value of encryption number (-n). Example1: Enter message: Hello World! Enter encryption key: 5 Mjqqt Btwail Example2: Enter message: Mjgqt Btwqil Enter encryption key: -5 Hello World!Please I would like in Python language or c# language the code for Vigenere Cipher WITH GUI but I want the program to encrypt and decrypt both English and Arabic letters, to further explain if the user enters Arabic letters, the program does the encryption or decryption and the same for English language.
- Text Encryption Encryption plays an important role in protecting messages that are transmitted across the network. There are many symmetric and asymmetric encryption techniques that can be used in order to encrypt text messages. Some of these techniques are Caesar, Rows-Columns Transposition, Rail- fence, and Playfair cipher encryption as well as advance encryption algorithms. In this project, you are required to write a code that is capable of encrypting any given text (or text file) into a cipher text using any two different methods. You should prompt the user to choose the method that they would like to encrypt their text from a given list. Challenge: develop your code to decrypt the cipher text that is encrypted above Example: Assume the text TO SERVE AND TO PROTECT is required to be encrypted using Row-Column with the password ALERT Then the text message in Rows-Columns Transposition will become: TVTTSAPCOEOEENRTRDOX. The same text message in Rail-fence with depth of 4 would…In this problem, you will implement a transposition cipher that, instead of dividing the original text into odd and even characters, separates it into three sets of characters. As an example, we will use this 1977 quote by Digital Equipment Corp. president Ken Olson -- "There is no reason anyone would want a computer in their home." (Spaces are represented with the square u-like character.) There is no reason anyone would want a computer in their home. Rail 1: T r S d i t i h a C. e Rail 2: e a u a u in h Rail 3: a W n. m m Example three-rail transposition. The resulting encrypted text is produced by reading the text horizontally, i.e., adding the three rails: Rail 1 + Rail 2 + Rail 3 = **“Trinrs yeoda cpeitihehesoeoao u naournhro.e annnwlwt mt e m" (without the quotes). Requirements: Implement the three-rail transposition cipher above, placing your code in the file p4_2.py (template I provided, replace comment at the beginning of the file with your own code). Feel free to develop your…Write a Python program to implement Caesar cipher. Caesar cipher is used to encrypt text by replacing each letter by another letter that comes after it in the alphabet by a fixed number of letters (encryption number n). If the last letter of the alphabet (letter 'z') is reached, the program continues to count from the beginning of the alphabet (letter 'a'). The user enters the text and the encryption number (n), and the program prints the encrypted text. The program can be used to decrypt an encrypted text by entering the encrypted text and the negative value of encryption number (-n).
- Experimenting with AES-”S symmetric key cipher. Note: You may use any programming language that provided libraries for AES. Descrion: This assignment consists of two parts:PART 1: write a program that uses AES-12/1 to decrypt a message. The program should be named "decrypt", and should deal with three files that contain the encrypted text as a stream of bytes, the 128-bit key for decryption stored as a stream of bytes, and file outcome of the decryption, respectively. o To test this program, here's an example of an encrypted message a. its 128-bit secret key PART 2: you will try to use "brute force" to decrypt an encrypted message, where you only have Sirrst 96-bits of the 12S-bit secret key (last 9 bytes of the secret key are he program should be called "findk", and should deal with two files that contain the encrypted text as a stream of bytes and the first 96-bits of the key, respetively. The program should decryptedn standard the the missing h6177 of the key in hexadecimal,…Simple Encryption. Write a java program that reads from a file specified by the user and encrypt the content of the file using a simple shifting technique. Also, ask the user to input the shift size. Output the encrypted message to another file whose filename is also provided by the user. For example, Shift size: 1 Message read from the file: Hello Encrypted message: Ifmmpin C++ language Magic Decoder Ring. A one-time pad is a coding device that uses each character of a key string only once to encode and decode a corresponding character in a message string. Thus, the first character in the key is used to encode and decode the first character in the clear message, the second character in the key is used with the second character in the message, etc. No portion of the key is reused in subsequent messages, making for a very solid coding system, assuming a randomly generated key. You will need to create a class titled MagicDecoderRing that contains the variables and functions needed for obtaining the clear and key texts, encoding and decoding the messages, writing out the encoded message etc. You will need to instantiate an instance of this class in your main function to run your program and encode and decode messages. You need to further break your MagicDecoderRing code down into many small functions that each can be described with a single sentence…
