Write a C++ program that implements the following two cases: Case 1: Encrypt files with certain extension using AES-CBC-256. Case 2: Decrypt encrypted files. Input Format: The program should be executed using the following command format: project1 Where: 1. project1: is the name of the executable after compilation. 2. casenumber: should accept ONLY two possible values only: (1) for case 1 and (2) for case 2. Any other input should be rejected. 3. In case 1 you should use inputfile-key to encrypt all files (within the current directory) with the given extension using AES-CBC-256. 4. In case 2 you should decrypt all encrypted files using inputfile-key. Output Format: 1. If case 1 is selected, then: all the required files should be encrypted. If file file_name.ext is encrypted, then the new encrypted file should be named as file_name.ext.enc. The original file should be deleted, and a summary of encrypted file names should be printed on the terminal. 2. If case 2 is selected, then: all encrypted files should be decrypted, original file names should be restored, encrypted files should be deleted, and a summary of all file names should be printed on the terminal. Submission Guidelines: 1. Use openssl package through the command line. 2. Do NOT use salt.
