Hi Romain,
I found a python script on github that lists all your items from Enpass. https://github.com/steffen9000/enpass-decryptor/blob/master/Enpassant.py
Clearly, Enpass is doing additional encryption of data column for unknown reasons.
Hi Ariel
You can try these steps:
Quit Enpass(if running).
Go to user Document Folder-->select Enpass Folder-->delete it.
Now when you open Enpass it will display welcome scrren
Try these steps:
Uninsatll the Enpass app.
Create a empty keychain with same master password that you are using on other devices.
Now sync with dropbox.
