In Laravel, you can use the Crypt
facade to encrypt and decrypt data. The Crypt
facade provides a simple interface for encrypting and decrypting data using symmetric encryption.
To encrypt data in Laravel, you can use the encrypt
method of the Crypt
facade. This method takes the data you want to encrypt as an argument and returns the encrypted data as a string.
Here is an example of how to use the Crypt
facade to encrypt data in Laravel:
use Illuminate\Support\Facades\Crypt;
$encrypted = Crypt::encrypt('my secret data');
In this example, the Crypt::encrypt
method will return an encrypted version of the string 'my secret data'
.
To decrypt the data, you can use the decrypt
method of the Crypt
facade:
$decrypted = Crypt::decrypt($encrypted);
echo $decrypted; // output: 'my secret data'
The Crypt
facade uses the AES-256-CBC algorithm by default, but you can specify a different algorithm using the setCipher
method:
Crypt::setCipher('AES-128-CBC');
Note that the Crypt
facade uses a secret key to encrypt and decrypt data. The secret key is automatically generated when you install Laravel and is stored in the APP_KEY
environment variable. You should keep this key secret, as it is used to secure your encrypted data.
It’s important to note that the Crypt
facade is intended for simple, low-security applications and should not be used for sensitive data. If you need to secure sensitive data, you should use a more secure encryption method, such as public-key encryption.
