DataLocker Encryption Basics


Hello I’m Sunil with DataLocker and today’s video is all about data encryption. Now we’ve come to a place in time where the convenience of being so connected means that we’re constantly at risk of having our private information fall into the wrong hands. The old saying “information is power” has never been more true and the effects of a data breach can be devastating for both companies and the customers that they serve. So what is data encryption? Well, simply put, encryption uses an algorithm to turn plain text, or an image, into a randomized string of code called “ciphertext”. It then takes an encryption key to decrypt that ciphertext back into plaintext that you and I can understand. The encryption key is something that only you or the intended recipients should have access to and encryption can be enforced by either software or hardware. The history of encryption actually goes all the way back to 600 BC where the ancient Spartans use a device called a Scytale to send secret messages during battle. Now modern computer encryption began in the early 1970s when IBM formed a crypto group and this group, designed a block cipher to protect customers’ data which became known as the “data encryption standard” or “DES” until it was cracked in 1997. In 2000, the “advanced encryption standard” or “AES” superseded DES as the de-facto encryption method and is currently considered the gold standard for encryption and approved for use in classified US government information. AES offers 128, 192, and 256-bit encryption verses the 56-bit encryption in use by DES and here at DataLocker, we use a version of AES in all of our encryption products. Now AES uses a couple of different modes; the first is called “ECB” which stands for “electronic code book” ECB is the most basic form of block cipher encryption and is typically used only to send very short messages or initiate other ciphers. “CBC” or “cipher block chaining” is an advanced mode of AES encryption. With CBC mode, each ciphertext block is dependent on the previous calculated ciphertext block which prevents patterns from forming in the ciphertext. Now if you’re an IT expert in an industry like finance or healthcare, legal or government, you know that encryption isn’t an option, it’s absolutely mandatory and encryption is an art and a science and yes it’s incredibly complex but the best encryption systems are very easy to implement and utilize while being virtually impossible to crack And here at DataLocker we like to call that “Simply Secure”. If you have any questions feel free to drop them in the comments below and until next time, I’m Sunil.
