[comb]

Hello,

I would like to know how is encrypted data during uploading from iOS device to Dropbox using "Official Objective-C SDK for the Dropbox API v2". What the security methods are used?

Thanks in advance.

All Dropbox API connections require TLS. (Specifically, the Dropbox API servers currently support TLS 1.0, 1.1, and 1.2.)

In the API v2 Objective-C SDK, we use `NSURLSession` to make the connections:
