title: Storing the OAuth credentials from DropBox securely in a Database for later use
body: <p>I am building a web app which will use the DropBox API to save data to a users folder. There are 2 parts to the site: an ASP.NET MVC Front End and a Windows Service. At the moment, I was planning on dumping the oauth string and user Id from the authorisation request to database, and use that in both the service and website calls, but how should I store that information? Should I encrypt it or not? And if so, any recommendations on how? For example, if the database is encrypted, how do I store the Encryption key? </p>
