Yea NO. NSL&#x27;s can&#x27;t do that. At worst they will tell you to release and data that you have and your private keys. At best they will tell you to make sure you archive everything and don&#x27;t permanently destroy records in case they are required in the future.
They cannot force you to add backdoors or create a weak crypto , although they can indirectly suggest you to do that and its then on the company if they do so.
