后端加密

<?php
function encryptString($data, $key) {
    $iv = openssl_random_pseudo_bytes(16);
    $encrypted = openssl_encrypt($data, 'aes-256-cbc', $key, OPENSSL_RAW_DATA, $iv);
    $result = base64_encode($iv . $encrypted);
    return $result;
}

$key = "YourSecretKey"; // 替换为您自己的密钥
$data = "Hello, World!";
$encryptedData = encryptString($data, $key);

echo $encryptedData;
?>

前端代码

<script>
function decryptString(encryptedData, key) {
	const rawData = CryptoJS.enc.Base64.parse(encryptedData);
	const iv = CryptoJS.lib.WordArray.create(rawData.words.slice(0, 4));
	const ciphertext = CryptoJS.lib.WordArray.create(rawData.words.slice(4));

	const decrypted = CryptoJS.AES.decrypt(
		{ ciphertext },
		CryptoJS.enc.Utf8.parse(key),
		{ iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }
	);

	return decrypted.toString(CryptoJS.enc.Utf8);
}

const key = "YourSecretKey";
const u = decryptString("后端加密后的字符串", key);
</script>
