<p>I'm trying to create a PHP equivalent of this JS code using CryptoJS: </p> <pre class="brush:php;toolbar:false;">function aesEncrypt (data) { const key = 'GSTEGSTEjdfheyhdHSHSHSHDHHDHmdjjdn12ndndn5r='; const iv = '\0'; const cipher = CryptoJS.AES.encrypt(data, CryptoJS.enc.Base64.parse(key), { iv: CryptoJS.enc.Utf8.parse(iv), // Parse IV padding: CryptoJS.pad.Pkcs7, mode: CryptoJS.mode.CBC }) return cipher.toString() }</pre> <p>The result of js code: pHjpwiyKq7Rf4dFcBMbm1w==</p> <p>This is PHP code I wrote by reading other stackoverflow questions. But it doesn't return the same result. </p> <pre class="brush:php;toolbar:false;">$plaintext = "plainText"; $method = 'aes-256-cbc'; $key = base64_encode("GSTEGSTEjdfheyhdHSHSHSHDHHDHmdjjdn12ndndn5r="); $iv = hex2bin('00000000000000000000000000000000'); $ciphertext = openssl_encrypt( $plaintext, $method, $key, OPENSSL_RAW_DATA, $iv ); $ciphertext = base64_encode($ciphertext); echo $ciphertext;</pre> <p>Result of PHP code: YJOMi2vISmEXIjUZls3MA==</p>

function encryptData($data, $key, $iv) {
  $cipher = "aes-256-cbc";
  $options = OPENSSL_RAW_DATA;

  $encrypted = openssl_encrypt($data, $cipher, $key, $options, $iv);
  $encrypted = base64_encode($encrypted);

  return $encrypted;
}

$message = "消息";
$key = "我的秘密密钥";
$iv = "我的iv";

$encrypted = encryptData($message, $key, $iv);

echo $encrypted;

$key = base64_decode("GSTEGSTEjdfheyhdHSHSHSHDHHDHmdjjdn12ndndn5r=");
