CheckMyHTTPS

This mobile app allows you to check if your encrypted web traffic (SSL/TLS) towards secure Internet servers (HTTPS) is being intercepted.

Normally, a secure website has to prove its identity to your browser by sending a certificate validated by a recognized certificate authority. Interception techniques generate dynamically forged certificates in order to fool the user into believing that his connection is secure. This mobile app checks that the received certificate is the right one. This app will compare that the certificate received by the client from a visited HTTPS website matches the certificate seen by a remote check server, ensuring that no interception is taking place. If they are different, your connection might be listened to! This allows us to prove the interception.
