Encrypted database and secure storage

Hello every body, i need for an app to encrypt the database, so i’ve found sqlcipher but with the new version, the window support is stopped.

So i must found and other solution.

For now, i think to use lokijs for generate some database base in NOSQL, but it’s not secure, so i would store it on the secure storage.

SO, i ve some question :

  1. Have you got a way to secure data on a device (other than secure storage)
  2. What it’s the size of secure storage ?
  3. It’s possible with ionic to add a password protection to a json file for example? And in this case is ti a good pratice?

Thank a lot guy
