Inspecting packets during a file transfer with an iOS application such as Google Photos. How would one know from packet inspecting if uploading a file is done securely despite being on a public network?
So far I know that a handshake occurs using the TLS protocol after that most of the data is delivered through TCP on port 443 and some Application Data through TLS. Is this normal behavior for an encrypted connection?
Furthermore, I know the data sent is mostly gibberish, but how can one be sure that all the packets are sent using a secure connection? I mean could you not send the data unencrypted on port 443 and having the data just being displayed as compressed data?
Does anyone know more about Google Photos and their encryption practices for downloading and uploading data with both photos and video? I just want to know if it is safe to use Google Photos on a public network.
Could one conclude that it is likely safe to use Google Photos, even on a public wifi? If you consider that to be the case please state why, if not please also give your opinion.
