Encryption is commonly used to disguise messages on the internet. A Caesar cipher performs a shift of all of the characters in a string (based on their ASCII values, see Table 1.2), e.g. h e l l o  m j q q t The example shows a shift with a distance of 5 characters, i.e. h(ASCII:104)  m(ASCII:109) Write a Python program that ask the user to input a line of plaintext and the distance value and outputs an encrypted text using a Caesar cipher, with the ASCII values range from 0 through 127. The program should work for any printable characters.
2 Please help me, I am using Java and it has to be AES As part of this project, you need to consider the following steps in your implementation: 1. With an AES encryption algorithm 2. Sender: Given a document X, write a program that can encrypt X with a passsword. Let’s say the password-protected document is Y 3. Receiver: Given Y, write a program that can ask the user to enter a password and perform decryption process to extract the original document X 4. During your implementation, you can also consider how to incorporate the following case: how a given document can be securely shared with several users. For example, if X is a document, then your platform can support multiple (authorized) users to securely access X.
this is python programming Create a function based on the following information: Your mission is to encrypt a secret message (text only, without special chars like "!", "&", "?" etc.) using Caesar cipher where each letter of input text is replaced by another that stands at a fixed distance. For example ("a b c", 3) == "d e f" Input: A secret message as a string (lowercase letters only and white spaces) Output: The same string, but encrypted Return: The same string, but encrypted
Need help with this c++ problem In encryption, plain text is the normal, human-readable text. Cipher text is the encrypted message. These are the two functions you'll be writing. One will encrypt plain text and the other will decrypt cipher text. void cipher(istream& in, ostream& out, unsigned key)void plaintext(istream& in, ostream& out, unsigned key) You are going to read from the parameter in and write to the parameter out. Treat the two parameters, in and out, just as you would cin and cout. In fact, if you want to encrypt the characters you type from the keyboard, and have the output appear in the console, you can just call cipher(cin, cout, 5) from your run function and everything that you type will be shifted to the right by five characters. Both of these functions are filter functions, so they will use data loops. Here is the pseudocode for the cipher() function: cipher(in, out, key):read each character (c) from inshift the character c right by keywrite c to out…
USE PYTHON Suppose a machine sells bottles of Coca-Cola (Coke) for 50 cents and only accepts coins in these denominations: 25 cents, 10 cents, and 5 cents. In a file called coke.py, implement a program that prompts the user to insert a coin, one at a time, each time informing the user of the amount due. Once the user has inputted at least 50 cents, output how many cents in change, the user is owed. Assume that the user will only input integers, and ignore any integer that isn’t an accepted denomination.

Solve in Python: Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first five letters of the last name, followed by the first letter of the first name, and then the last two digits of the number (use the % operator). If the last name has less than five letters, then use all letters of the last name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: JordaM91 Ex: If the input is: Kanye West 2024 the output is: Your login name: WestK24
6. Write a Python program that inputs a sentence string by the user and counts thenumber of words in the sentence.7. Write a Python program that inputs a large integer and outputs this integer withcommas inserted at every 3 digits. For example, when 5231908126 is entered,the output is 5,231,908,126.
