为什么我的解密函数不适用于 CryptoJS？

问：

我对加密很陌生，我正在尝试将 CryptoJS 与 AES 用于 ReactNative 项目。要求是使用加密数据从端点获取数据，但是当我尝试解密时，我的代码返回一个空字符串。

在PHP中，端点数据由以下函数加密：

    $KEY;
    $IV_LENGTH = 16;

这里的键是静态的，已经由 getKey（） 函数生成。

    public function encrypt($plain_text){
        global $KEY;
        $iv = $this->generateIV();
        $encrypted = openssl_encrypt($plain_text, 'aes-256-cbc', hex2bin($KEY), OPENSSL_RAW_DATA, $iv);
        return base64_encode($iv.$encrypted);
    }

    public function decrypt($encrypted){
        global $IV_LENGTH;
        global $KEY;
        $data = base64_decode($encrypted);
        $iv = substr($data, 0, $IV_LENGTH);
        $encryptedData = substr($data, $IV_LENGTH);
        return openssl_decrypt($encryptedData, 'aes-256-cbc', hex2bin($KEY), OPENSSL_RAW_DATA, $iv);
    }

    public function getKey(){
        $salt = random_bytes(256);
        $iterations = 999;
        $passphrase = 'orpheus';
        return hash_pbkdf2("sha512", $passphrase, $salt, $iterations, 64);
    }

    public function generateIV(){
        global $IV_LENGTH;
        return openssl_random_pseudo_bytes($IV_LENGTH);
    }

JS中测试的加密函数（这里的KEY和PHP代码中的KEY是一样的）：

    import { Buffer } from 'buffer';
    import {KEY} from '../constants/Constants'
    import CryptoJS from 'react-native-crypto-js';

    const CryptoJSAesEncrypt = (text) => {
        let iv = CryptoJS.lib.WordArray.random(16);
        let encryptedData = CryptoJS.AES.encrypt(text, KEY, {iv: iv});
        let encrypt = iv+encryptedData;
        return (Buffer.from(encrypt).toString('base64'));
    }

CryptoJSAesEncrypt，输入 textoo！ 返回例如： NGFjMjdkODMxNTNlMGYwZmM1ZDYyNTc1MTcwMjBkNDNVMkZzZEdWa1gxOWlUcXA4NXphaEx1VjdlbncwVEVxcm9vUENrSXlWUWZvPQ==

    const CryptoJSAesDecrypt = (encrypted) => {
        let data = Buffer.from(encrypted, 'base64').toString('ascii');
        let iv = data.substring(0,16);
        let encryptedData = data.substring(16);
        let decrypted = CryptoJS.AES.decrypt(encryptedData, KEY, {iv: iv});
        return decrypted.toString(CryptoJS.enc.Utf8)
    }

编辑：

我使用 js 函数中包含的十六进制解码进行了测试

const CryptoJSAesEncrypt = (text) => {
    let iv = CryptoJS.lib.WordArray.random(16);
    let encryptedData = CryptoJS.AES.encrypt(text, CryptoJS.enc.Hex.parse(KEY).toString(), {iv: iv});
    let encrypt = iv+encryptedData;
    return (Buffer.from(encrypt).toString('base64'));
}

const CryptoJSAesDecrypt = (encrypted) => {
    let data = Buffer.from(encrypted, 'base64').toString('ascii');
    let iv = data.substring(0,16);
    let encryptedData = data.substring(16);
    let decrypted = CryptoJS.AES.decrypt(encryptedData, CryptoJS.enc.Hex.parse(KEY).toString(), {iv: iv});
    return decrypted.toString(CryptoJS.enc.Utf8);
}

测试：

    const text = 'YES!';
    const a = CryptoJSAesEncrypt(text);
    console.log('Text: ',text); //Text:  YES!
    console.log('Encryption: ',a); //Encryption:  MjAwYjdiMmNhODkwNDBiZDYxYTY2MTczNThiNjIwZDRVMkZzZEdWa1gxK0FwQ0F5d3VtMnc1ait4NGVVMkFVOFZ3OFczajZMcjJZPQ==
    console.log('Decryption: ', CryptoJSAesDecrypt(a)); //Decryption:

解密不返回任何内容。
