CryptoJS (crypto.js) 为 JavaScript 提供了各种各样的加密算法。目前已支持的算法包括：
- MD5
- SHA-1
- SHA-256
- AES
....
这里我们演示aes对称加密数据传输，下面列出crypto-js的几个重要链接

js前端演示代码：
<script src="./crypto-js-3.1.9-1/crypto-js.js"></script>
<script type="text/javascript">
/**加密
*
* @param data
* @returns {string}
*/
function encrypt(data) {
let text = JSON.stringify(data);
text = CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse(text)).toString();
let key = CryptoJS.enc.Utf8.parse('1234567887654321'); //为了避免补位，直接用16位的秘钥
let iv = CryptoJS.enc.Utf8.parse('1234567887654321'); //16位初始向量
let encrypted = CryptoJS.AES.encrypt(text, key, {
iv: iv,
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.ZeroPadding
}).toString();
return CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse(encrypted)).toString();
}
/**解密
*
* @param data
* @returns {string}
*/
function decrypt(data) {
let encrypted = CryptoJS.enc.Utf8.stringify(CryptoJS.enc.Base64.parse(data)).toString();
let key = CryptoJS.enc.Utf8.parse('1234567887654321'); //为了避免补位，直接用16位的秘钥
let iv = CryptoJS.enc.Utf8.parse('1234567887654321'); //16位初始向量
let decrypted = CryptoJS.AES.decrypt(encrypted, key, {
iv: iv,
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.ZeroPadding
}).toString(CryptoJS.enc.Utf8);
return CryptoJS.enc.Utf8.stringify(CryptoJS.enc.Base64.parse(decrypted)).toString();
}
let data = {"username": "admin", "pwd": "passwd"};
let encrypt_data = encrypt(data);
let decrypt_data = decrypt(encrypt_data);
console.log(decrypt_data);
</script>
php后端演示代码：
/**加密
* @param $data
* @return string
*/
function encrypt($data)
{
$key = "1234567887654321";//秘钥必须为：8/16/32位
$iv = "1234567887654321";
$base64_str = base64_encode(json_encode($data));
$encrypted = openssl_encrypt($base64_str, "aes-128-cbc", $key, OPENSSL_ZERO_PADDING, $iv);
return base64_encode($encrypted);
}
/**解密
* @param $data
* @return mixed
*/
function decrypt($data)
{
$encrypted = base64_decode($data);
$key = "1234567887654321";//秘钥必须为：8/16/32位
$iv = "1234567887654321";
$decrypted = openssl_decrypt($encrypted, 'aes-128-cbc', $key, OPENSSL_ZERO_PADDING, $iv);
return json_decode(base64_decode($decrypted), true);
}
$data = ['username'=>'admin','pwd'=>'admin'];
$encrypt=encrypt($data);
$str=decrypt($encrypt);
var_dump($str);
