JS 解密 Laravel 加密字符串

这就是你如何使用 AES-256-CBC 作为密码解密用 Laravel 编码的 JavaScript 文本。

使用 CryptoJS 4.0...

// Created using Crypt::encryptString('Hello world.') on Laravel.
// If Crypt::encrypt is used the value is PHP serialized so you'll 
// need to "unserialize" it in JS at the end.
var encrypted = 'eyJpdiI6ImRIN3QvRGh5UjhQNVM4Q3lnN21JNFE9PSIsInZhbHVlIjoiYlEvNzQzMnpVZ1dTdG9ETTROdnkyUT09IiwibWFjIjoiM2I4YTg5ZmNhOTgyMzgxYjcyNjY4ZGFkNTc4MDdiZTcyOTIyZjRkY2M5MTM5NTBjMmMyZGMyNTNkMzMwYzY3OCJ9';

// The APP_KEY in .env file. Note that it is base64 encoded binary
var key = 'E2nRP0COW2ohd23+iAW4Xzpk3mFFiPuC8/G2PLPiYDg=';

// Laravel creates a JSON to store iv, value and a mac and base64 encodes it.
// So let's base64 decode the string to get them.
encrypted = atob(encrypted);
encrypted = JSON.parse(encrypted);

console.log('Laravel encryption result', encrypted);



// IV is base64 encoded in Laravel, expected as word array in cryptojs
const iv = CryptoJS.enc.Base64.parse(encrypted.iv);

// Value (chipher text) is also base64 encoded in Laravel, same in cryptojs
const value = encrypted.value;


// Key is base64 encoded in Laravel, word array expected in cryptojs
key = CryptoJS.enc.Base64.parse(key);

// Decrypt the value, providing the IV. 
var decrypted = CryptoJS.AES.decrypt(value, key, {
  iv: iv
});

// CryptoJS returns a word array which can be 
// converted to string like this
decrypted = decrypted.toString(CryptoJS.enc.Utf8);

console.log(decrypted); // Voilà! Prints "Hello world!"
