Don’t Believe These 5 Myths About Encryption!

Philip Bates 14-07-2016

You’ve probably heard a bit about encryption, but it sounds like something too complex, too specialist, to consider using yourself.


But encryption is simply a means of scrambling your data into seemingly-random characters, called ciphertext, which can only be unscrambled into meaningful information when an authorized user enters the correct decryption key. The key is just a passphrase, password, or PIN Why Passphrases Are Still Better than Passwords & Fingerprints Remember when passwords didn't have to be complicated? When PINs were easy to remember? Those days are gone, and cybercrime risks mean fingerprint scanners are next to useless. It's time to start using passcodes... Read More .

It’s a lot more straightforward than most think. Nonetheless, you might feel a little too in-the-dark to make use of encryption, so let’s bust some encryption myths!

1. Only Big Corporations Use Encryption

The root of this myth likely stems from the idea that only international organisations are worth targeting, but that’s simply not true. If it were, there’d be little need for security suites protecting your own PCs.


Your data, even the basic information, is worth stealing Here's How Much Your Identity Could Be Worth on the Dark Web It's uncomfortable to think of yourself as a commodity, but all of your personal details, from name and address to bank account details, are worth something to online criminals. How much are you worth? Read More because it can all be sold on by scammers. Breaching your home security is one way to achieve identity theft. In order to keep your personal information private, it needs to be scrambled. Data you enter online is even encrypted (on sites using HTTPS What Is HTTPS & How To Enable Secure Connections Per Default Security concerns are spreading far and wide and have reached the forefront of most everybody's mind.

But recent breaches and flaws may have dented your trust in the cryptographic protocol. Fortunately, SSL is adapting, being upgraded - here's how. Read More .


Actually, encryption is used more often than you think. As of last year, Apple claims to have sold 700 million iPhones, with an estimated 101 million users in the USA alone. And if those people are security-conscious, they’ll have activated passcode locks. That’s a form of encryption because if an unauthorized user tried to scroll through their contacts, peruse their photos, or traverse Twitter, they wouldn’t be able to without the correct passcode.

That’s just one example (another is WhatsApp WhatsApp Encryption: It's Now the Most Secure Instant Messenger (Or is it?)

But what does this mean for you? Here's what you need to know about WhatsApp encryption.

2. It’s Really Hard to Implement

You might be thinking, “Sure, it’s easy to turn encryption on when you’ve got an iPhone, but I bet it’s more difficult on Android. And what about my PC? I bet that’s near impossible to encrypt!”


Admittedly, difficulties vary depending on the mobile OS, but not that greatly. Windows 10 Mobile just requires you to go on Settings > System > Device encryption. Since Android Lollipop 8 Ways Upgrading to Android Lollipop Makes Your Phone More Secure Our smartphones are full of sensitive information, so how can we keep ourselves safe? With Android Lollipop, which packs a big punch in the security arena, bringing in features that improve security across the board. Read More , encryption comes as default (unless you’re getting a low-end model). Smartphone manufacturers have realized the need for this added layer of security.

But it’s pretty simple on PCs and laptops as well. Device encryption was first introduced for Windows 8.1, and any PCs with Windows 10 are supposed to use it as default — on the condition that you sign in using a Microsoft account. To check whether you’re using encryption (and to enable it), go on Settings > System > About. If the device encryption option isn’t there, you won’t be able to protect your files without something like BitLocker or these alternatives TrueCrypt Is Dead: 4 Disk Encryption Alternatives For Windows TrueCrypt is no more, but fortunately there are other useful encryption programs.

The level of control you can have over encryption is astonishing too. You can actually encrypt individual files. How? On Windows, you right click on a file or folder and go Properties > Advanced > Encrypt contents to secure data; when you close the Advanced tab, click Apply.

Likely perpetuated by the Factory Resets on smartphones, most people think these will wipe your device completely clean. You’re passing on a clean slate, right? Not at all. While in most cases, the eventual recipient of your hardware won’t have the abilities or inclination to restore data about you, a determined criminal generally can.

If you do plan on getting rid of a device, either encrypt all its data then do a Factory Reset, or destroy it completely. Take a hammer to it or burn it.

The exception is the Factory Reset option on iPhones: that really does wipe the slate clean.

4. Encryption Always Affects Performance

This is true in rare cases, but for the most part, you don’t need to worry about performance lag. It’ll be negligible, and for the most part, unnoticeable.

The reason this myth does the rounds is because your PC or smartphone has to decrypt all its contents before you get access to its databases. It stands to reason that it’ll take a while. Can you be bothered to wait each time you try to get onto your files?

Fortunately, manufacturers know their audience expects this level of security and that many would be put off if it’s at the expense of functionality. If your device is pretty new, you shouldn’t have a problem with performance. Just think of how quickly an iPhone starts up after a passcode is entered. Barely any time at all.

Disk-level encryption generally impacts performance less than application-level; even then, drives with medium- to high-end processors support Intel Advanced Encryption Standard New Instructions (AES-NI), which is designed to improve the speed of applications using encryption keys. Some people claim that encryption speeds things up!

There are, of course, exceptions. Aged PCs won’t be able to cope that quickly, but if they’re that old, the system in general will be slower than recent versions regardless.

5. Encryption is 100% Secure

Don’t get me wrong: encryption is a great way of protecting your private information, but it’s not fool-proof. Nothing ever is. Encryption is just a great start.

Recently, we’ve heard a lot about data breaches: the so-called Celebgate How A "Minor" Data Breach Made Headline News & Ruined Reputations Read More was one of the most high-profile leaks, but further notable password breaches have happened in just the past couple of months, including 32 million Twitter How to Check If Your Twitter Password Has Leaked & What to Do Next Apparently over 32 million Twitter accounts and passwords have been leaked, according to TechCrunch.

[Tech News Digest] Facebook is tracking everybody across the Web, millions of MySpace credentials are up for sale, Amazon brings Alexa to your browser, No Man's Sky suffers a delay, and Pong Project takes shape. Read More . That’s an astonishing amount of hacks.

Encryption keys aren’t unbreakable. iPhones were purported to be the most secure mobile OS What Is The Most Secure Mobile Operating System? Battling for the title of Most Secure Mobile OS, we have: Android, BlackBerry, Ubuntu, Windows Phone, and iOS. Which operating system is the best at holding its own against online attacks? Read More , mostly thanks to their supposedly-impregnable encryption; if you don’t want anyone getting in, you set up a passcode and not even Apple can get into it. But earlier this year, that was proved false when a hacker, paid by the CIA, got into the smartphone of an alleged terrorist.

Probably the main weakness in encryption is storage of the keys. Whistleblower, Edward Snowden says:

“Properly implemented encryption does work… If you have a centralized database of keys, that is a massive target. We’ve got to focus on end points, we’ve got to focus on the keys, [make them] more defensible.”

Is Encryption Worth It?

Definitely. It’s certainly not absolute, but it’s a simple and, in the majority of cases, effective way of keeping your personal information private.

    "but it's not fool-proof. Nothing ever is"

    Nothing ever is foolproof ? seems like a foolproof statement. :)
