<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>

Try this:
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;In the PHP code, the key must be Base64 decoded , not Base64 encoded:
$key = base64_decode("GSTEGSTEjdfheyhdHSHSHSHDHHDHmdjjdn12ndndn5r=");With this change, the required ciphertext is created.
Please note that if 0
is passed in the fourth parameter of theopenssl_encrypt()call instead ofOPENSSL_RAW_DATA, the encryption The file will be Base64 encoded by default. Therefore, explicitly Base64 encoding the ciphertext is unnecessary.Please remember that static IVs are not safe. Typically during the encryption process, a random IV is generated and passed along with the ciphertext to the decryption party (usually spliced together).
