How does commander.passwordEncrypted work?

commander.passwordEncrypted works by prompting the user to enter a password in the command line interface, and then encrypting the entered password using the SHA-256 hashing algorithm.

When commander.passwordEncrypted is called, it displays a message to the user via the command line interface, prompting them to enter a password. The function then waits for the user to enter a password, which is typically done via the keyboard.

Once the user has entered a password, commander.passwordEncrypted encrypts the entered password using the SHA-256 hashing algorithm, which generates a fixed-length hash value that represents the original password.

This encrypted password can then be used in a program, such as for secure authentication or authorization purposes.

commander.passwordEncrypted is a synchronous function, which means that it blocks further execution of the program until the user has entered a password and the function has returned the encrypted version of that password.

const program = require("commander");
const crypto = require("crypto");

// Add a command with a password prompt and encryption
program
  .command("login")
  .description("Log in with a password")
  .action(() => {
    const password = program.passwordEncrypted("Enter your password: ");
    const hashedPassword = crypto
      .createHash("sha256")
      .update(password)
      .digest("hex");
    console.log(`Hashed password: ${hashedPassword}`);
  });

// Parse the command-line arguments
program.parse(process.argv);

In this example, we first import the commander and crypto modules. We then use the program object to add a new command named "login" with a description of "Log in with a password". We use program.passwordEncrypted to prompt the user to enter a password and encrypt the entered password using the SHA-256 hashing algorithm. We store the entered password in a variable named password, and then use crypto.createHash to create a new hash object that uses the SHA-256 algorithm. We then use the update method to add the entered password to the hash object, and the digest method to generate the final hash value as a hexadecimal string. We store the hashed password in a variable named hashedPassword, and then log this value to the console. Finally, we use program.parse to parse the command-line arguments and execute the appropriate command. When the "login" command is executed, the user is prompted to enter a password and the entered password is encrypted and hashed using the SHA-256 algorithm.
