Is there a hacker near you? Is your employer watching your traffic?
This is the fastest way to check.
This app will check the SHA fingerprint of the SSL certificate as seen by the Android device and will compare it to the fingerprint of the same website as seen on an external network. It will catch a case of a Man-in-the-Middle (MITM) listening in to your HTTPS encrypted browsing.
This convenient tool does not require you to record certificate fingerprints. It handles everything for you including checking on a different network. You get an immediate answer to the question of spying.
