Laravel provides robust encryption features to protect sensitive information, including symmetric encryption algorithms like AES-256-CBC, AES-128-CBC, and others. To use Laravel's encryption features, the first step is to update the config/app.php file with the default encryption algorithm, specify the encryption key, and configure other encryption-related settings. The Crypt facade in Laravel offers a simple and consistent API for encrypting and decrypting data using methods such as encrypt() and decrypt(). Before diving into message encryption, it's essential to generate a unique encryption key, which can be done by running the php artisan key:generate command. To encrypt a message, use the encrypt method, while to decrypt an encrypted message, use the decrypt method. The example application demonstrates how to encrypt and decrypt messages in Laravel using the Crypt facade.
