What is Data Encryption and How Does it Work?

Data encryption protects your data from being seen, hacked, or stolen. VPNs provide data encryption at the consumer  avg.com/retail   level avg antivirus free, but how about end-to-end encryption? Is a VPN the best option, or are there other solutions out there? What does data encryption even mean? Find out with our www.avg.com/activate guide to everything you avg internet security need to know about data encryption.

What is data encryption?

Data encryption is a system that encodes your data so other people can’t read it. Consider this: No, that’s not a massive typo Install Avg With License Number activation — that’s the phrase “What is data encryption?” encrypted with a simple Caesar cipher avg antivirus free, or shift cipher. Each letter is replaced by the letter that follows it in the alphabet avg internet security, so when you see the encrypted phrase, it’s just gibberish. You can’t decrypt it if you don’t know the encryption system.

Data encryption works along the same lines, but with far more complex encryption systems. These transform regular data www.avg.com/activate, stored as plaintext, into what’s known as “ciphertext” — a seemingly nonsensical string of letters avg.com/retail   , numbers, and symbols. You can only unscramble the data, or decrypt it, with a specific decryption key.

Why use data encryption?

Data encryption is all about protecting your personal information from anyone who’d like to get their hands on it. This idea stems from humanity’s avg antivirus free long history of encoded communications, the use and study avg internet security of which is known as cryptography. Some of these encryption systems, such as the writing used in the Renaissance-era Voyinch manuscript, still remain uncracked, even with Install Avg With License Number activation the aid of modern computing.

So why is data encryption important? In short, using encryption protects your personal data. You can use data encryption to safeguard yourself against a multitude of online threats, including identity theft, hacking, and fraud.

Many businesses also use encryption algorithms in network security to defend against spyware and other malware. Anyone who manages to obtain encrypted data won’t be able to read it — preventing hackers from gaining access to business secrets. That means data encryption also protects avg.com/retail    against  avg internet security certain avg antivirus free strains of ransomeware that hijack data and threaten to publish it unless a ransom is paid.

 How can encryption be used to protect information?

Did you know that you’re benefiting from data encryption nearly every time you use the internet? Here are a few uses of encryption www.avg.com/activate that you may encounter in your daily online life:

HTTPS encryption

Many modern websites feature HTTPS encryption — you’ll know because the URL begins with https, or because your browser shows you a little Install Avg With License Number activation padlock icon in the address bar. Check your address bar now, and you’ll see these indicators avg internet security here on our site. AVG Signal’s looking out for you.

HTTPS encryption protects your internet traffic while it travels between your device and the website you’re using, preventing anyone from either listening in or altering the data while it’s in transit. You should never divulge any sensitive  avg antivirus free personal data, such as credit card numbers, while on an unsecured avg internet security website with plain old HTTP. If you don’t know how secure a certain site is, it’s always best to do a quickwebsite safety check before entering any personal information.

Email encryption

Gmail and Outlook — two of the most widely used email platforms — encrypt all emails by default. The encryption they provide should be avg.com/retail    sufficient for the average email user, but there are more secure options www.avg.com/activate available. Both Gmail and  avg antivirus free Outlook offer upgraded encryption with premium accounts, and Proton mailis a securely encrypted email service that anyone can use.

Secure messaging apps

many messenging apps protects user from data encrytion. Signal and Wickr are two popular options providing end-to-end encryption: the data is encrypted all the way from the sender to the receiver.

Cryptocurrency

If you’ve dabbled at all in cryptocurrencies such as Bitcoin (BTC) or Ethereum (ETH), you’ve also enjoyed the protections www.avg.com/activate of data encryption — though if you’re savvy enough to be using these, you probably already Install Avg With License Number activation knew that. Cryptocurrencies protect their users by encrypting transactions and storing them in a shared avg internet security historical avg antivirus free record known as the “blockchain.” Once a transaction joins the blockchain, it can’t be reversed or forged.

VPNs

VPNs are a popular solution for data encryption — you can even download a VPN on your mobile phone for encryption on the go avg.com/retail   . If you’re on an unsecured public Wi-Fi network, a VPN is an ideal solution for keeping your data safe avg internet security. We’ll explore VPNs in more detail later in this piece Install Avg With License Number activation, but for now, think of them as on-demand data encryption that’s both convenient and secure.
