iTunes Connect: Submit An app to the App Store

Hi there; I’m preparing to submit my app. One feature of my app is the QR Code. It allows the user to input text message and then convert it into QR code, which then it can be sent to other people by clicking on the share button.
Apple ask me this question: Is your app designed to use cryptography or does it contain or incorporate cryptography? (Select Yes even if your app is only utilizing the encryption available within Apple’s operating system.). I don’t know how to answer this question.

Another question, Apple ask me:

Does you app contain, display, or access third-party content?

If, for example, I purchase a license for audio to put into the app, do I tick “Yes” since it is contain third-party content, the background of the audio. Is that right?

Any suggestions will be appreciated.
