What is correct method to encrypt and decrypt data in magento 2?

Question

I am creating magento 2 custom module, where I am getting some data using API call. I need to store that data in my custom table. Before storage I need to encrypt that data. I think there is default encrypt function for that. I have used Mage::helper('Mage_Core_Helper_Data')->encrypt($value). But no success.

You can use it this way:

use Magento\Framework\Encryption\EncryptorInterface as Encryptor;

in the construct function :

$this->encryptor = $encryptor;

then call encrypt function to encrypt:

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

and to decrypt:

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