What resources or references can be helpful for understanding encryption standards and algorithms in PHP?

Understanding encryption standards and algorithms in PHP can be complex, but there are several resources and references that can be helpful. The PHP manual provides detailed information on encryption functions and algorithms available in PHP, such as OpenSSL and Mcrypt. Additionally, online tutorials and guides on cryptography and PHP encryption can offer practical examples and explanations to deepen your understanding. 

// Example code snippet 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 IV

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

echo "Original data: $data\n";
echo "Encrypted data: " . base64_encode($encrypted) . "\n";
echo "Decrypted data: $decrypted\n";
