Does Arduino Ethernet/wifi shield support OAuth V1?

I am contemplating with adding dropbox API to a project to automatically upload files to dropbox.com (a cloud storage). The API says it needs OAuth V1, some sort of authentication over HTTP?! Will the official ethernet or wifi shield support this type of stuff or some secure connections? Maybe not but I thought I should ask before going for a raspberry pi. Thanks.

First line under authentication. This is a python SDK but the first few paragraphs are generic.
