README

A Laravel package for json data encryption and decryption using RSA pair keys.

Installation

You can install the package via Composer:

composer require paymetrust/laravel-data-encryption

How to use

1. Generate RSA keys First you'll need to generate a public and private RSA key. To do this, follow the instructions below

openssl genrsa -out private.key 2048
openssl rsa -in private.key -pubout -out public.key

You can then store your private and public keys in the storage directory of your laravel application in any subfolder or directly in the root of the folder.

1. Laravel project configuration Once your keys have been generated and stored, you will now add these two variables to the environment file : SSL_PUBLIC_KEY_PATH="your/storage/path/file.key" and SSL_PRIVATE_KEY_PATH="your/storage/path/file.key". Once this has been done, add these configurations to your config/app.php file so that the package can take them into account.

'ssl_public_key_path' => env('SSL_PUBLIC_KEY_PATH'),
'ssl_private_key_path' => env('SSL_PRIVATE_KEY_PATH'),

1. Encrypt and decrypt data Now you can use the package to encrypt and decrypt json data. Here's an example of how to do:

To encrypt :

This method is useful if you wish to encrypt json data. For example, if you store data in your database such as tokens or keys formatted as json strings, it would be useful to hide this information for data integrity purposes.

DataEncryption::encrypt($jsonString, config('app.ssl_public_key_path'));

To decrypt :

DataEncryption::decrypt($encryptedString, config('app.ssl_private_key_path'));
