Laravel Crypt Encryption

### Example Usage

Here's how you can use `encryptString()` and its counterpart `decryptString()`:

#### Encrypting a String

use IlluminateSupportFacadesCrypt;

$encryptedValue = Crypt::encryptString('Sensitive Data');
echo $encryptedValue; // Outputs an encrypted string

#### Decrypting a String

use IlluminateSupportFacadesCrypt;

$decryptedValue = Crypt::decryptString($encryptedValue);
echo $decryptedValue; // Outputs 'Sensitive Data'

### How It Works
– **`encryptString($value)`**: Encrypts the provided string and returns the encrypted value.
– **`decryptString($encryptedValue)`**: Decrypts the previously encrypted string and returns the original value.

### Error Handling
If the decryption fails (e.g., if the data has been tampered with), an `IlluminateContractsEncryptionDecryptException` will be thrown.

Here's an example of using try-catch for error handling:

use IlluminateSupportFacadesCrypt;
use IlluminateContractsEncryptionDecryptException;

try {
    $encryptedValue = Crypt::encryptString('Sensitive Data');
    $decryptedValue = Crypt::decryptString($encryptedValue);
} catch (DecryptException $e) {
    echo 'Failed to decrypt: ' . $e->getMessage();
}

### Configuration
The encryption key used by Laravel is defined in the `.env` file:

APP_KEY=base64:YOUR_RANDOMLY_GENERATED_KEY

Make sure that this key is kept secret and never shared publicly, as it is crucial for the security of your encrypted data.

### Use Cases
– **Storing sensitive data** in the database, such as API tokens or user credentials.
– **Encrypting data** before sending it to the frontend.
– **Securing session data** or other temporary storage.

### Notes
– The encrypted data is base64-encoded, so it can safely be stored in databases or sent over HTTP without further encoding.
– The `encryptString()` and `decryptString()` methods are suitable for short pieces of data. If you need to encrypt large files, consider using Laravel's `Storage` facade with encryption support.
