What are the potential issues with using rawurldecode in PHP for encryption and decryption processes?

Using rawurldecode in PHP for encryption and decryption processes can lead to security vulnerabilities, as it is not designed for encryption purposes. It can expose sensitive data and make it easier for attackers to exploit the system. To address this issue, it is recommended to use proper encryption and decryption functions provided by PHP, such as openssl_encrypt and openssl_decrypt. 

// Encrypt data
function encryptData($data, $key) {
    return openssl_encrypt($data, 'aes-256-cbc', $key, 0, '1234567890123456');
}

// Decrypt data
function decryptData($data, $key) {
    return openssl_decrypt($data, 'aes-256-cbc', $key, 0, '1234567890123456');
}
