What is Encryption? - A Quick Overview

Over the last year, the public has been sitting on the sidelines watching as the debate on encryption unfolds. It’s an emotionally charged subject that has the public divided.

Some people are confused because they aren’t entirely sure how encryption works or what it even is. So, here’s a little background for you.

 

ENCRYPTION TURNS YOUR 'STUFF' INTO OTHER 'STUFF'

When you make a purchase online, send a text message, or email another person, this data is considered to be ‘in transit.’ During this period, a hacker can drop in and swoop your data up for themselves.

Encryption takes your ‘data in transit’ and scrambles it with a sophisticated mathematical algorithm to prevent this swooping from occurring. This algorithm creates an unintelligible combination of your data that can be incredibly difficult and near impossible to unscramble unless you have the specific decryption key.

It's similar to how codes and ciphers work, on a very advanced level.

 

THERE ARE LEVELS OF ENCRYPTION

There are different types of encryption, namely asymmetric and symmetric.

Symmetric encryption involves a single key to encrypt and decrypt information while asymmetric encryption involves both a public and private key.

Asymmetric encryption is often used for messaging, and the decryption process only takes place after the private key gives permission to the public key.

 

IT ISN'T JUST FOR THE INTERNET OR PHONES

Encryption wasn’t just created to protect your online accounts and purchasing activity. Encryption is also used to protect your information in other instances, like when you use an ATM or if you rely on a WiFi-connected device to secure your home.

 

IT ISN'T MEANT TO HIDE BAD THINGS

One of the main reasons encryption exists, and continues to exists, is to protect and preserve your privacy. It’s not designed to hide illegal activities. In fact, quite the opposite.

Encryption is partially intended to hide your life from people attempting to carry out illegal activities against you like identity theft, stalking, and fraud. But, that’s not all it’s meant for.

Encryption is also intended to keep your conversations and daily activities as private as you want them to be. Just because you aren’t doing anything worth hiding, doesn’t mean people should be able to watch or hear you live your life.
