Store

The store is an encrypted data store where we can store JSON data.

We can store application-specific settings (for instance, for local clients).

Contact information could also be stored in the store.

DB on client

"contacts" ==> collection
   1 ==> "address: jaytaph!,  full name:  Joshua Thijssen..... ",
   2 ==> "address: acalatrava!,  full name:  Antonio Calatrava..... ",

"foo" ==> collection
   "bar" ==> collection
      "config" ==> jsonblob of config

And the client will keep a keys store with the checksums of all the data

"keys" ==> collection
  "/contacts/1" ==> modification timestamp
  "/contacts/2" ==> modification timestamp
  "/foo/bar/config" ==> > modification timestamp

On the first connection to the server, and in order to keep the data in sync with the server (and other clients) the client will send a GET request to get the metadata of the DB stored on the server

GET /store?since=timestamp

[
  sha256("/contacts/1"),
  sha256("/contacts/2"),
  sha256("/foo/bar/config"),
]

The client will download the updated data or push the new data on the client

GET /store/sha256("/contacts/1"))

{ 
  timestamp: timestamp,
  data: blob (which is aes_encrypt("address: jaytaph!,  full name:  Joshua Thijssen..... "))
}

PUT /store/sha256("/contacts/1"))

{ 
  timestamp: timestamp,
  data: blob (which is aes_encrypt("address: jaytaph!,  full name:  Joshua Thijssen..... "))
}
