How to encrypt decrypt file pls write documentation encrypt decrypt file

[polypixeldev]

Can you clarify, please? If the file is text formatted (ex. utf8) you can get a string of the file with fs.readFileSync, and then pass that into your preferred cipher (ex. AES).

For example (assuming test.txt is utf-8 encoded):

const passphrase = 'secret key';
const string = fs.readFileSync('test.txt', {encoding: 'utf-8'});
const encryptedString = cryptoJS.AES.encrypt(string, passphrase);

You could then decrypt it like this:

let decryptedString = cryptoJS.AES.decrypt(encryptedString, passphrase).toString(cryptoJS.enc.Utf8);
