PHP 및 Vue.js 개발을 위한 보안 모범 사례: 민감한 데이터 저장소 보호

// 加密函数

// 解密函数
function decrypt($ciphertext, $key) {
    $ciphertext = base64_decode($ciphertext);
    $iv_size = openssl_cipher_iv_length('AES-256-CBC');
    $iv = substr($ciphertext, 0, $iv_size);
    $ciphertext = substr($ciphertext, $iv_size);
    return openssl_decrypt($ciphertext, 'AES-256-CBC', $key, OPENSSL_RAW_DATA, $iv);

// 使用示例
$key = 'YourEncryptionKey';

    echo "密码验证成功
";

    echo "密码验证失败
";

// 使用axios发送POST请求
axios.post('/api/save-sensitive-data', {
