I would like to use the driver of AES encryption,
but every time the CRYP->CR run, it will go to hardfault.I have no idea the reason.Thanks!

Have you checked if F401 has this peripheral?
You probably didn't, so I will tell you. It does not have it.Only F415, F417, F437 and F439 have it.Options

The standard parts don't have the CRYP/HASH peripheral due to export controls. There are specific part# which have them.
ST has a crypto library that supports software and hardware implementations. You have to meet specific requirements to order it.http://www.st.com/web/en/catalog/tools/PF259409
