Why is the secure storage locked?

Hi SCN-Team,

I have a question regarding the secure storage in hana studio.

I am using hana via cloudshare and recently my secure storage was locked.

I´ve solved this problem by the following post:

I´ve read that this can happen if the the secure storage file is corrupted.

My question is how the secure storage is getting corrupted and is this a general problem or can this problem be fixed by sap?

Thank you for your replies.

Regards,

Nicole
