使用 crypto.createCipheriv() 在用 browserify 匯出 js 時會出錯, 解法:

原有程式:
const crypto = require('crypto');
const algorithm = 'aes-256-ctr';
const ENCRYPTION_KEY = 'Put_Your_Password_Here'; // or generate sample key Buffer.from('FoCKvdLslUuB4y3EZlKate7XGottHski1LmyqJHvUhs=', 'base64');
const IV_LENGTH = 16;
function encrypt(text) {
let iv = crypto.randomBytes(IV_LENGTH);
let cipher = crypto.createCipheriv(algorithm, Buffer.from(ENCRYPTION_KEY, 'hex'), iv);
let encrypted = cipher.update(text);
encrypted = Buffer.concat([encrypted, cipher.final()]);
return iv.toString('hex') + ':' + encrypted.toString('hex');
}
function decrypt(text) {
let textParts = text.split(':');
let iv = Buffer.from(textParts.shift(), 'hex');
let encryptedText = Buffer.from(textParts.join(':'), 'hex');
let decipher = crypto.createDecipheriv(algorithm, Buffer.from(ENCRYPTION_KEY, 'hex'), iv);
let decrypted = decipher.update(encryptedText);
decrypted = Buffer.concat([decrypted, decipher.final()]);
return decrypted.toString();
}
let a = encrypt('node-cheat');
let b = decrypt(a);
console.log(a, b);
把 require(‘crypto’) 換成 require(‘crypto-browserify’)
