前言

对接一个第三方平台，其使用AES对称加密

代码

//方式1
//加密
function enAES($originTxt, $key='Q6Mr6rDpn12iZb'){return base64_encode(openssl_encrypt($originTxt, 'AES-128-ECB',$key, OPENSSL_RAW_DATA));
}//解密
function deAES($originTxt, $key='Q6Mr6rDpn2iOaZl')
{$data = base64_decode($originTxt);return openssl_decrypt($data, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);
}//方式2
