Php 解密.net中laravel生成错误生成的AES。填充无效，无法删除
我在php中使用AES加密，并将数据发送到.netPhp 解密.net中laravel生成错误生成的AES。填充无效，无法删除,php,.net,laravel,encryption,aes,Php,.net,Laravel,Encryption,Aes,我在php中使用AES加密，并将数据发送到.net Padding is invalid and cannot be removed 当我在php进行解密时，它提供了完美的输出。我确信解密时存在一些配置问题。我已经尝试过填充模式。零 我的php代码类如下所示： $inputKey = env('SALT_KEY', ''); $blockSize = 256; $aes = new AES($inputText, $inputKey, $blockSize); $enc
Padding is invalid and cannot be removed
$inputKey = env('SALT_KEY', '');
$blockSize = 256;
$aes = new AES($inputText, $inputKey, $blockSize);
$enc = $aes->encrypt();
$aes->setData($enc);
$dec=$aes->decrypt();
echo "After encryption: ".$enc."<br/>";
echo "After decryption: ".$dec."<br/>";

我需要与.net中的laravel/php中生成的数据相同的数据。我无法重现该问题。因此，您应该发布完整的示例数据：两个代码的明文、密钥、IV和密文。在任何情况下都需要优化，例如，使用哪种机制将随机生成的IV传递给接收者（我假设静态IV仅用于测试目的）？在PHP代码中，
