Using Amazon EC2; transferring files

I can't speak to Amazon but I just wrote an article on using Google Drive. I imagine must of the process is the same once you get past the authentication specifics. So I would suggest looking at the amazon API documents. The google api docs were a huge help. And, In the case of Google, there was a .net library that implements all the functions.

Second, you don't have to convert everything to vb. You can add a second project into your solution, make it a c# library, then add the code files for the 'overhead' stuff. Add a reference to it in the vb project and all those classes become available in vb for your consumption. You don't need the source code for opensslkey... just the classes it exposes. So wrap them as-is and just use the resulting dll. Don't be afraid of c#... it is just vb with semi-colons. :-)
