$textToEncrypt = "My super secret information.";
$encryptionMethod = "AES-256-CBC";  // AES is used by the U.S. gov't to encrypt top secret documents.
$secretHash = "25c6c7ff35b9979b151f2136cd13b0ff";

//To encrypt
$encryptedMessage = openssl_encrypt($textToEncrypt, $encryptionMethod, $secretHash);

//To Decrypt
