load key

[youxi]

Hi:

load key Is that what storing key in HSE means? The second time on, can these keys still be used to encrypt and decrypt?

[youxi]

In addition, if format key, will all keys be deleted?

Hi @youxi 

yes, load key means that a key is either stored to flash or to RAM. Keys stored in flash will be available also after next reset / power cycle, RAM keys won't be available.

Format catalogue function will erase all the keys.

There's new set of HSE examples which could help:

wow. I was looking for a long time for this answer. I did not see this information in HSE reference, maybe I missed. Thanks @lukaszadrapa 

So, am I understand right?

First, define keys and Key catalog. format catalog, init and define key handles. then load them in your code.

Later, I can remove keys, format catalog and load key functions from code for later usage.

Hi @anakha 

Yes, that's correct. Just notice that key catalogs can be formatted only in CUST_DEL life cycle.
