Create encrypt string in Aura component

Hello all,
I have an aura component where I need to encrpty a string that contains vlaues from the component.  Can I do this within the component JS?  Or does the data need to be sent to a controller and then pulled back again?  I am encrypting  a string and sending it to an external site when a user saves their record.
Thank you,
P

1) Import crypto-js.min.js as a static resource

2) No problem detected from the locker console

Ensure that your code is compatible with Lightning Locker by running the code with Locker enabled. Run the code a second time with Locker disabled to see if any errors are due to Lightning Locker restrictions.

Thank you for teh reply Alain.
So after add the crypto-js.min.js file as a static resource.
How do I pass in the values to encrypt?  CryptoJS.AES.encrypt('Name', 'address');
This can be done in the helper JS correct?
Thanks for your help.
