Are there any alternative encryption methods or libraries that could be more reliable than mcrypt in PHP?

The mcrypt library in PHP is considered outdated and insecure, as it has not been maintained for several years. A more reliable alternative for encryption in PHP is to use the OpenSSL extension, which is actively maintained and updated. By switching to OpenSSL, you can ensure better security for your encryption needs. 

// Example of using OpenSSL for encryption in PHP
$data = "Hello, world!";
$key = openssl_random_pseudo_bytes(32); // Generate a random key
$iv = openssl_random_pseudo_bytes(16); // Generate a random initialization vector

$encrypted = openssl_encrypt($data, 'AES-256-CBC', $key, 0, $iv);
$decrypted = openssl_decrypt($encrypted, 'AES-256-CBC', $key, 0, $iv);

echo "Encrypted: " . $encrypted . "\n";
echo "Decrypted: " . $decrypted . "\n";
