[web] Google Photos and the unguessable URL … a look at how the “Open URLs” in Google Photos work … ‘Why is that public URL more secure than it looks? The short answer is that the URL is working as a password. Photos URLs are typically around 40 characters long, so if you wanted to scan all the possible combinations, you’d have to work through 10^70 different combinations to get the right one, a problem on an astronomical scale. “There are enough combinations that it’s considered unguessable,” says Aravind Krishnaswamy, an engineering lead on Google Photos. “It’s much harder to guess than your password.” Because web traffic for Photos is encrypted with SSL, it’s also kept secret from anyone on the network who might be listening in.’
