Keep Conversations Private with End-to-End Encryption Messaging


Messaging is one technological advance that most cannot live without. But most of us would like to rest assured that what we type will be for the eyes of the receiver only, and not a mysterious third party. Regardless of paranoia or worry about hacking, encryption is a sure fire way to protect messages as they leave your finger tips. End-to-end encryption ensures that only the sender and the recipient can read the message. The message is first encrypted on your phone, then sent, and decrypted on the receiving side. Telecom providers, government agencies, and the company that hosts the service itself, cannot read your messages. The provider couldn’t even hand over messages if subpoenaed, because the provider would not have the ability. Hackers that infiltrate the service platform still would not be able to read your encrypted messages.

This sounds almost too good to be true, and not all encryption services are created equal. Encrypted, does not imply end-to-end encryption. Services that encrypt messages between endpoints of transmission, means that conversations are stored encrypted on the platform’s servers, which is not entirely bad. However, since the platform encrypted them they can also decrypt them.

The best end-to-end encryption services on the market today are as follows:

Telegram – Has been around for a while now, which might aid with the biggest hang up on the app, inviting all your friends to join. This over-the-top service does not have the ubiquity of SMS messaging. The app does allow for individual messaging, group messaging for an unlimited number of users, or even public group messaging for a social network feel.

Signal – This is one of the easier applications to set up, automatically authenticating your phone number. It can be used as your default SMS application as well, eliminating hurdles found with over-the-top services. The color custimization for conversations helps with communication clarity, aka not sending the wrong text to the wrong conversation. In addition to private conversations and group conversations with unlimited users, this application also makes calls.

Wire – Wire is a cool alternative for the user that wants message encryption and creative license. The application allows for doodling, location sharing, image sending, and video recording. Despite the feature initiatives, the application doesn’t support some of the escalated group messaging features, and is best used for private one-on-one conversations.

WhatsApp – By far the most popular, this application offers end-to-end encryption and the lure of over a billion users. Hopefully meaning less people you have to convince to install and use a different messaging service. The application is owned by Facebook, which just recently announced they would be using phone numbers and some other account information from  WhatsApp. Hmm. Despite worry, the application proves to be a user friendly messaging alternative.

Google Apps not Quite Comparable to Exchange

Recently I was asked to perform a migration of a few users from their current Exchange Server 2003/2007 environment over to Google Apps.  Although the migration process was fairly simple to execute, users quickly found that there were a few things lacking in the Google Apps offering.

I had users that were accustomed to the collaboration features that were very easy in Exchange, like contact and calendar sharing, which are not so easily done in Google Apps.  Google Apps now provides an API to help accomplish contact sharing, however, I’m not a developer and neither are any of my users.  That being said, I don’t think this is a viable option for us.  The good news is that this API is relatively new, and maybe someone will develop something that is useful for sharing contacts – something that is easy for me and my users to implement.

The calendar sharing was much better, but also lacks an important function.  When using the Outlook plugin (which allows you to use Outlook as your Google Apps client), the only way for a user to see another user’s calendar would be to grant full access to the calendar being shared.  If the user does not have full access, they can only see free/busy information and not the appointments on the calendar.

As I said earlier, the migration process went really well, and there are several very good options for executing the migration.  However, my users leveraged the power of Outlook and Exchange were left a little disappointed with Google Apps.  If you have very simple email and calendaring needs, and are a smaller business operation, Google Apps may be just fine.  If you are looking for an alternative for your in-house Exchange server, you might be happier looking into Microsoft’s Hosted Exchange solution.
