Got nothing to hide? Think again.
You may change your mind after reading this great article by Zack Whittaker in the ZDNet web site at http://www.Zdnet.Com/article/simple-security-step-by-step-guide/.
I will add one item to Whittaker’s statements about Signal, the popular cell phone app for encrypted messaging. Everything he wrote is correct but he neglected to mention that the app is only secure if both persons in the conversation are using Signal. If only one person uses Signal and exchanges text messages with non-Signal users, the texts sent and received are unencrypted and just as vulnerable to online spies and hackers as any other text messaging app.
I like Signal and use it often. You can download Signal here.
