-Soledad Server documentation
-============================
-
-A U1DB server that stores data using CouchDB as its persistence layer.
-
-.. contents::
- :local:
-
-General information
--------------------
-
-This is written as a Twisted application and intended to be run using the
-twistd command. To start the soledad server, run:
-
-.. code-block:: bash
-
- twistd -n web \
- --class=leap.soledad.server.entrypoint.SoledadEntrypoint \
- --port=X
-
-An systemd script is included and will be installed system wide to make it
-feasible to start and stop the Soledad server service using a standard
-interface.
-
-Server database organization
-----------------------------
-
-Soledad Server works with one database per user and one shared database in
-which user's encrypted secrets might be stored.
-
-User database
-~~~~~~~~~~~~~
-
-Users' databases in the server are named 'user-<uuid>' and Soledad Client
-may perform synchronization between its local replicas and the user's
-database in the server. Authorization for creating, updating, deleting and
-retrieving information about the user database as well as performing
-synchronization is handled by the `leap.soledad.server.auth` module.
-
-Shared database
-~~~~~~~~~~~~~~~
-
-Each user may store password-encrypted recovery data in the shared database.
-
-Recovery documents are stored in the database without any information that
-may identify the user. In order to achieve this, the doc_id of recovery
-documents are obtained as a hash of the user's uid and the user's password.
-User's must have a valid token to interact with recovery documents, but the
-server does not perform further authentication because it has no way to know
-which recovery document belongs to each user.
-
-This has some implications:
-
- * The security of the recovery document doc_id, and thus of access to the
- recovery document (encrypted) content, as well as tampering with the
- stored data, all rely on the difficulty of obtaining the user's password
- (supposing the user's uid is somewhat public) and the security of the hash
- function used to calculate the doc_id.
-
- * The security of the content of a recovery document relies on the
- difficulty of obtaining the user's password.
-
- * If the user looses his/her password, he/she will not be able to obtain the
- recovery document.
-
- * Because of the above, it is recommended that recovery documents expire
- (not implemented yet) to prevent excess storage.
-
-The authorization for creating, updating, deleting and retrieving recovery
-documents on the shared database is handled by `leap.soledad.server.auth`
-module.
