cblair / encrypt_decrypt_files.js
Created August 21, 2024 20:06
// WIP
// Objective: Create a Node.js script that encrypts text files within a specified directory using asynchronous programming. This script should encrypt the content of each text file using a basic Caesar Cipher for simplicity, then save the encrypted content to a new file in a different directory. The process should handle multiple files concurrently, support both encryption and decryption modes, and log the completion of each file operation.
// Requirements:
// Mode Selection: The script should accept a mode argument (encrypt or decrypt) as the first command-line argument to determine the operation mode.
// Directory Arguments: Accept two additional command-line arguments for the input directory (containing text files to process) and the output directory (where encrypted or decrypted files will be saved).
const { assert } = require("node:console");
const { argv } = require("node:process");
const { readdir, readFile } = require('node:fs/promises');
