Rick Wright commented on LIBCLOUD-266:
--------------------------------------
I'm picking up where Ziyad left off to get GCE supported in libcloud. Right
now, I have a basic working version that removes all dependency on gcelib
(which is deprecated anyway) and also does not depend on any additional third
party libraries (with one exception, as noted below). I hope to have a patch
available in the coming weeks.
A note on authentication: There are two basic ways for authenticating to GCE
using OAUTH2:
The first is with a "service account". This gives you a private key file and
you authenticate based on that key. The problem is that it requires signing
the request using an SHA256withRSA (aka RSASSA-PKS1-V1_5-SIGN with the SHA-256
hash). There is no sane way to generate that signature using only Python
built-in libraries, so using a service account would require the use of the
PyCrypto library.
The second authentication method is the "installed application" flow. This
essentially gives you a URL to visit and log-in/authorize the application.
After authenticating, the user is given a code that they would paste in at a
prompt. From there, a temporary access token and a refresh token are
generated. At that point, the refresh token would be stored locally and used
to provide authentication for the application. This second method does not
require any crypto functions, but does require a one-time interactive setup.
The solution I'm working on will support both, but PyCrypto will not be
required unless the user of the library wants to use the service account flow.
(i.e. There won't be any import errors if a person doesn't have PyCrypto and
authenticates with the installed application flow or uses other Providers).
Anyway, I would appreciate any feedback you have at this point.
