"""This module is used to control authentication/authorization of Kobo sync requests.
|
||||
This module also includes research notes into the auth protocol used by Kobo devices.
|
||||
|
||||
Log-in:
|
||||
When first booting a Kobo device the user must sign into a Kobo (or affiliate) account.
|
||||
Upon successful sign-in, the user is redirected to
|
||||
https://auth.kobobooks.com/CrossDomainSignIn?id=<some id>
|
||||
which serves the following response:
|
||||
<script type='text/javascript'>
|
||||
location.href='kobo://UserAuthenticated?userId=<redacted>&userKey<redacted>&email=<redacted>&returnUrl=https%3a%2f%2fwww.kobo.com';
|
||||
</script>
|
||||
And triggers the insertion of a userKey into the device's User table.
|
||||
|
||||
Together, the device's DeviceId and UserKey act as an *irrevocable* authentication
|
||||
token to most (if not all) Kobo APIs. In fact, in most cases only the UserKey is
|
||||
required to authorize the API call.
|
||||
|
||||
Changing Kobo password *does not* invalidate user keys! This is apparently a known
|
||||
issue for a few years now https://www.mobileread.com/forums/showpost.php?p=3476851&postcount=13
|
||||
(although this poster hypothesised that Kobo could blacklist a DeviceId, many endpoints
|
||||
will still grant access given the userkey.)
|
||||
|
||||
Official Kobo Store Api authorization:
|
||||
* For most of the endpoints we care about (sync, metadata, tags, etc), the userKey is
|
||||
passed in the x-kobo-userkey header, and is sufficient to authorize the API call.
|
||||
* Some endpoints (e.g: AnnotationService) instead make use of Bearer tokens pass through
|
||||
an authorization header. To get a BearerToken, the device makes a POST request to the
|
||||
v1/auth/device endpoint with the secret UserKey and the device's DeviceId.
|
||||
* The book download endpoint passes an auth token as a URL param instead of a header.
|
||||
|
||||
Our implementation:
|
||||
We pretty much ignore all of the above. To authenticate the user, we generate a random
|
||||
and unique token that they append to the CalibreWeb Url when setting up the api_store
|
||||
setting on the device.
|
||||
Thus, every request from the device to the api_store will hit CalibreWeb with the
|
||||
auth_token in the url (e.g: https://mylibrary.com/<auth_token>/v1/library/sync).
|
||||
In addition, once authenticated we also set the login cookie on the response that will
|
||||
be sent back for the duration of the session to authorize subsequent API calls (in
|
||||
particular calls to non-Kobo specific endpoints such as the CalibreWeb book download).
