Decrypt/Encrypt Function

[Kaesewuerfel]

How ist laravel decrypting and encrypting my strings?

[veelasky]

what do you mean by how?

if you refer to the usage (on how to use them), see documentation

use Illuminate\Support\Facades\Crypt;

// encrypt string to hash
Crypt::encryptString($string);

// decrypt encrypted to the original
Crypt::decryptString($encryptedValue);

But if you interested to on how it works, you can always go to the source code here.

TLDR; Laravel use openssl_encrypt() and openssl_decrypt() respectively to generate encrypted string, with the default cipher AES-128-CBC`
