Support changing password #13

Closed davidmigloz closed 6 years ago

It would be nice to be able to change the user-provided password easily.

This means that all the data has to be decrypted with the old password and re-encrypted with the new one.

It can be handy when you want to switch from a default password to a user-provided password. And for later when the user wants to change it.

Agree.

I added a first POC implementation of changePassword(). Was pretty straight forward and could easily be used to migrate null passwords.

@davidmigloz If you like you can have a look at it, I pushed it on feat-13-change-pw

It looks pretty good 👍

I'm working currently in adding the change password feature to the sample app.
