Your online safety, security, and privacy are of utmost importance, and AES encryption ensures you have all of it.

Sneak peek at AES encryption

Today, most services offer data encryption that converts a normal text into a Ciphertext – the unreadable form – to protect the users’ valuable information from prying eyes. Advanced Encryption Standard (AES) is the most reliable, secure, and fastest encryption model, ensuring robust protection against cyber-attacks and data theft. It codes the online information in several rounds and steps, depending upon the key sizes, after which the data appear gibberish to anyone without the required decryption key. Let’s learn more about AES encryption in this guide.

The world isn’t safe anymore. Unfortunately, it’s true not only for our physical space but online too. Hackers and other cybercriminals are always lurking around, looking for ways to gain access to your data. This can be pretty scary.

So, how would you ensure your online information remains safe wherever you may be?

The answer lies with encryption – the transformation of your data from readable to unreadable form to protect it from snoopers.

Today, encryption exists in various forms to protect your data at rest and during transit. Of all the types available, AES encryption is by far the most popular and widely used, such that it’s become the universal standard for keeping communication and information safe.

What makes AES so unique and useful? How does it ensure to provide thorough safety to my data? I hear you ask.

To answer these queries, this article focuses on what AES (Advanced Encryption Standard) is all about, its working mechanism, and its history. Also, I will elaborate on some security matters and answer pressing questions.

Let’s begin!

What is AES encryption?

Advanced standard encryption, technically referred as Advanced Encryption Standard (AES) is a safe and fast cipher that keeps your data away from the prying eyes.

Technically, it is the symmetric form of encryption where only a single key ciphers and deciphers the data. While this sounds simple, what makes AES the gold standard is the application of multiple rounds of encryption which makes the algorithm impossible to penetrate.
