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.Many user-created passwords are simple and easy to guess. Program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "q*s" to the end of the input string. i becomes ! a becomes @ m becomes M B becomes 8 o becomes . Ex: If the input is: mypassword the output is: Myp@ssw.rdq*s IN JAVA. USING LOOPS
