Add URL scheme for automation apps like IFTTT and Workflow

[tobihagemann]

Feature request by a user via email:

Is it possible to integrate an URL scheme into Cryptomator so that some of the more tedious processes can be levitated from using automation apps such as Launch Center Pro, IFTTT, and Workflow? It would really lighten the need for jumping from screen-to-screen and app-to-app if it was possible to trigger basic recipes such as: new pictures/documents arriving in local folder from either other identity or self and automatically one receives a notification and encrypting start and/or similar 'things' are triggered. The recipes themselves are made within aforementioned apps. However, an integrated URL scheme is needed within the app being called.

I'll update this issue with ideas on how the URL schemes could be defined. Thinking about it right now makes me believe that it's not simply done by "adding a URL scheme". Vaults get automatically locked so that a password is required, which would make automation apps unusable. That would probably mean that Cryptomator needs a setting for "always unlocked vaults". Or maybe some other idea. But yeah, this has to be discussed first. 😉

Just wanted to add this as documentation for future reference: Inter-App Communication (jump to "Using URL Schemes to Communicate with Apps")

Due to the recent acquisition of Workflow by Apple, I think this is becoming more interesting. However, I'm still unsure about opening up Cryptomator. We'd have to think about security. E.g., how should a file automatically being encrypted, if there is no UI for entering a vault password?
