Does Google use network encryption on it's Android apps like Gmail, Drive, Google Play, Docs, and others when doing authentication/data transfer? What type of encryption is it? Is it secure?

I have tried searching Google's help site about this and did not find a good answer. Can you provide me with some resources about the topic?

  • Can you give some context? Encryption of what exactly? Communication between the apps and the servers? Encryption on the device itself?

packet capture of android phone communicating with Google's server

Above is a packet capture of communication between my phone and Google's server( Apparently, TLS is used to protect data in transit. TLS is also used for your browser's connection to a HTTPS website so the security is comparable.

If transmitted over cellular networks, there is a second layer of encryption between your phone and your provider. The algorithm used could be A5/KASUMI depending on the network.


Google encrypts everywhere:

Security is a top priority for Google. We invest a lot in making sure that our services use industry-leading security, like strong HTTPS encryption by default. That means that people using Search, Gmail and Drive, for example, automatically have a secure connection to Google.

Its apps use HTTPS to communicate with its APIs.
