The ongoing password breaches and Snowden revelations about government surveillance have raised many questions about why cloud and email services don't encrypt data stored on their servers?
The revelations forced popular internet giants like Google and Yahoo to reflect on privacy and security issues, and the response began by strengthening their encryption, enabling HTTPS by default and removing the option to disable it.
A few days ago, Google admitted that its automated systems read the content of our messages, including incoming and outgoing emails, to provide us with personally relevant ads. This means that the internet giants generally encrypt our data, but they have the key, so they can decrypt it at any time they want.
Encryption is mandatory in the modern internet and services and should consider encrypting and decrypting our data locally so that no one can monitor it without us knowing. This encryption mechanism is called End-to-End Encryption, this means that the content of our messages should be known to us and our browser, but not to Google itself.
