Subject [jira] [Commented] (CXF-4431) Add support for OAuth2 'mac' token type
Date Tue, 24 Jul 2012 16:35:34 GMT


Sergey Beryozkin commented on CXF-4431:

Hi, here is the initial commit to the trunk:

will merge it later to 2.6.x.

Here are some comments on the modifications I did:
- Made relevant updates to get the latest draft supported
- I did quite a few refactorings, mainly to get all the Hmac and normalization work
done in one or two places.
- I did not introduce mac specific properties into ClientAccessToken - it needs to be able
to manage not only bearer/mac, but other types too,
it has the typed well-known properties all token share and then a map of parameters for keeping
the token specific extensions
- I've not added a NonceVerifier implementation yet, only the interface. I think the implementation
is actually pretty advanced :-), which is good,
  but I guess we need to think a bit more about whether we should ship it with CXF or may
be as part of the demo - may be we should get ECache-based store added, etc, need to think
- plus few other bits and pieces

Hope you will won't be disappointed with the changes I did. 

Overall it's a very good contribution - thanks for the effort. 
Few more minor updates may need to be done, like the queries normalization, etc, but it's
nearly there.

As a side note - I'd like to review if we can get this Mac-specific code available to other
OAuth projects once it settles down a bit, we can discuss it offline, I'll ping you here or
please ping me later on.

> CXF currently supports only the Bearer token type. This token type is not feasible for
use without SSL.
> OAuth2 specs out the 'mac' token type that requires request signing for authentication
using the access token. The spec is described here:
