What is the best approach for decrypting packets using PHP?

To decrypt packets using PHP, you can use the OpenSSL extension, which provides functions for encryption and decryption. You will need the encrypted data, the encryption key, and the encryption method used to encrypt the data. By using the openssl_decrypt function, you can decrypt the packets and retrieve the original data.

$encryptedData = "encrypted data here";
$encryptionKey = "encryption key here";
$encryptionMethod = "AES-256-CBC";

$decryptedData = openssl_decrypt($encryptedData, $encryptionMethod, $encryptionKey, 0, $encryptionKey);
echo $decryptedData;
