Privacy is an important issue in our society and maybe you are thinking: is my Whatsapp information safe? Whatsapp announced that the message you send is encrypted. Whatsapp use an encryption created by the company Open Whisper Systems.
The security only works for one-on-one messages, groupdiscussions and media messages are not encrypted. It involves complete end-to-end encryption, which means that Whatsapp itself can not see the content of messages.
Earlier, there were sometimes problems with the encryption. October 2013 a Dutch student showed that you can crack the messages and read it.
