How to Use Encryption and Decryption in Magento 2

According to recent market surveys, Magento is the most popular eCommerce development platform with a 29.1% of market share along with More than 247,900 online stores that run on Magento, including some of the leading brands like Canon, Coca-Cola, Ford, Nestle N Care and Burger king.

ECommerce sites are always on target of hackers because most of the personal & payment information Which is required to complete a sale is done within a store. Even though Magento is a pretty secure CMS compared to others, but still, it’s necessary to make sure that your Magneto store is secure against those hacking attacks. Magento provides timely updates of SUPEE patches which contains multiple security and functional fixes.

There are several things those are helpful to make your store attack proof against hackers, but one of the best ways to make it more secure is to use encryption and decryption algorithm into Magento stores which helps to transfer data securely from one source to another one.

What are Encryption & Decryption?

Encryption and Decryption is part of cryptography concepts which refer hidden or secret text in which, Encryption is the process of transforming information to unintelligible information and Decryption is the process of transforming encrypted information to its Original format again.

Generally, in this technique whenever a sender sends some data to receiver, it will be encrypted using secure key and at the second end, whenever receiver receives data from senders, the sent data will be decrypted using that secure key.

Default Magento, out of the box comes with functionality of encryption and decryption using EncryptorInterface class.
First of all, we need to define EncryptorInterface class as in our file

use Magento\Framework\Encryption\EncryptorInterface;

After that, we need to declare one variable inside our class.

protected $encryptor;

Now we have to create constructor of class.

$this->encryptor = $encryptor;

After that, we need to call encrypt function to encrypt the given information

$id='magecomp';
$encrypt = $this->encryptor->encrypt($id);

and to decrypt that information, we simply need to write following line.

$decrypt = $this->encryptor->decrypt($encrypt);

That’s it, now you can use or customize this code according to your need of encrypting inside your Magento store. Leave comment below if you are facing any issue while setting up encryption in to your Magento Store.
Happy Encoding!
