Feature request: encrypt notes and encrypt backups

[Searcher23]

It's very nice if we can encrypt notes and encrypt backups

[nullled]

Undoubtedly a must-have feature for the large majority of users that would take notice of this app in the first place. (including myself)

[Rbagman]

I would rather have the option to export backups in .html format and the ability to select the backup folder location (extSdCard or UsbDriveA, etc.).

As for encryption, I use Cryptonite.

Have you thought of using SQLCipher from Zetetic as a drop-in replacement for SQLiteDatabase (like SealNote does)? This way, the whole SQLite database would be encrypted, not only the note content itself. However, attachments would have to be encrypted individually.

Now that notes can be encrypted, can anyone tell me how to decrypt it manually ? I can't import my backup as this feature is not functionnal (see #384). I was able to salvage the unencrypted text as it was in plainfile but I can't figure out how to decrypt the encrypted notes :(

Can anyone help ? That would be very appreciated

Now that notes can be encrypted

How can be they? Did not find anything linked with encryption in 6.0.2.

I think it is called "lock"

Locking actually encrypts notes and when they're added to backup (now in JSON format) they keep their encryption.

For what concerns @cobalt59 comment: that seems nicely doable due to the SQLCipher's "transparent" nature but I'd have to perform some speed tests. At the time I started developing ON performances were so much more significant than now, that's why full encryption was been excluded. All of this without keeping in consideration attachments, that would require a specific process.

Add my +1 for encrypted backups and even for local storage.
