Conversations are safe from Hangouts of Google; During one AMA at Reddit, The Christopher Soghoian, τεχνολόγος στην Αμερικανική Ένωση Πολιτικών Ελευθεριών και εμπειρογνώμονας της τεχνολογίας επιτήρησης, ρώτησε τον David Lieber, διευθυντή της Google για την ασφάλεια πληροφοριών, γιατί η εταιρεία δεν αναφέρει περισσότερα πράγματα για το γεγονός ότι επιτρέπει σε κυβερνητικές αρχές την υποκλοπή των επικοινωνιών των χρηστών του.
Although Google never claimed that the service uses end-to-end encryption, has stated that the information you share on Hangouts "Encrypted, to be safe," whatever that means.
Salgado, on the other hand, happened to mention that “comments are encrypted at transport,” which, when explained in non-technical terms by user reddit_poly, means that once the conversations reach Google, the company can pretty much do whatever it likes with them, including making them available to the authorities .
After inadvertent confirmation, the website Motherboard contacted a Google representative who supported what Salgado said, that the company's messaging system does not use end-to-end encryption.
Not that this confirmation was necessary, as EFF had published a chart as part of their security campaign and Hangouts system. EFF says the Hangouts system is as safe as Facebook chat, which means that only two of the seven checkpoints proposed by the organization have passed.
In addition, in a report transparency that posted on their official website, Google revealed that they had collaborated with the US authorities in 2013 by allowing them to intercept data for legal reasons.
