Encryptions for images #12

Closed madurangae closed 4 years ago

madurangae commented 4 years ago

Hi! What is the recommended flow to encrypt images with this library? Thanks!

konstantinullrich commented 4 years ago

I would recommend reading the bytes of the Image and convert those to a base64 string, which you can encrypt.

I hope that helps. If you give me a few minutes, I'll try it

After some trying around, I concluded, It would be faster to encrypt the Images using a form of hybrid encryption.

For example, encrypt the Image with a synchronous encryption algorithm like AES and encrypt the key separately with an asynchronous algorithm. I know it's an extra step, but I'd reckon it'll improve the performance of your application.

Thanks for the great tip!! It makes total sense to use the hybrid approach you have mentioned.
