Question: is there an example of storing images and encrypting it

First of all great work. Huge respect. I owe you a big deal.

Well have a question though...

Is there an example of store an image/picture and encrypt it? I haven't been able to find any examples.

Well sembast is not really designed for that:

• binary blob must be json encoded somehow (base64 being a common solution) and decoded so it has some performance penalty
• there is no encryption support in sembast itself (although there is an example using an external encryption algorithm).
• If you use sembast codec to perform encryption, everything will be encrypted (not only the image)

My advice would be to store the image in an external file, keeping a reference to it in sembast.

If you do need to store the image in sembast, you can encode the image data as base64 and then either you encrypt the whole database (https://github.com/tekartik/sembast.dart/blob/master/sembast/doc/codec.md) or you encrypt only the image using any encryption algorithm you can find.
