Don't store sensitive personal data in commerce_payment_transaction

Hi,

With the new GDPR laws in place can we avoid storing sensitive data in this table in the database:

     ction_id' => array(
        'table' => 'commerce_payment_transaction',
        'columns' => array('transaction_id' => 'transaction_id'),
      )

(from what I can see it stores the callback from worldpay).
Like: postcode, cardType, address, email.

If possible at best will be to encrypt this data using the encrypt module. But if you can replace the data with ** would work too.
example "cardType";s:10:"**** ****"

Looking forward to your answer.
Thanks
