# Why is cybersecurity so important in the last couple of years? Are there any dangers? And how can you use VPN services to your advantage?

At the moment, there s an increased need for online security. Cybercriminals are developing better strategiesën for stealing data from unsuspecting, unsecured users. One way to prevent this is to encrypt your network. There are several encryption systems, **but 256-bit AES is the most popular** and perhaps the most secure.

In this article you will find everything you need to know about this καλύτερο vpn.

**What does 256-bit AES encryption mean?**

What does encryption mean? When you encrypt data, you take its raw form, known as plaintext, and perform an algorithmic function on it. This turns it into an encrypted ciphertext. The algorithm used in encrypting data is known as the key. Usually the key used for each encryption is a closely guarded secret. The only exception is the public key used in asymmetric encryption.

**In principle, there are two types of encryption.** Eéone has already been mentioned above, namely asymmetric encryption. The other is, as you can guess, symmetric encryption.

- Symmetric encryption is also called private-key cryptography. This is because the parties on both sides must share the same key used during encryption.
- Asymmetric encryption is also called public-key cryptography. You can also imagine it as one-way encryption. In this scenario, the two parties do not have to share the same privékey. The party on one side has the public key, and the other party has a private key.
- 256-bit encryption refers to an encryption technique where one party uses the 256-bit key to encrypt and decrypt files. It is one of the most secure encryption systems in the world. Other options include the 128-bit and 192-bit. However, these are not as secure. This encryption is used in modern security algorithms such as AES and SSL.

AES stands for Advanced Encryption Standard. The AES is an encryption algorithm that secures your online activities with a Nord VPN trial.

**Why was the 256-bit A****ES encryption developed?**

The United States government developed AES 256-bit to meet its needs. Before its creation, federal agencies in the US used a 56-bit symmetric key design. This was known as the Data Encryption Standard (DES) and was the creation of IBM. This was around the 1970s and this encryption lasted for almost 30 years.

As the years passed, however, it became clear that DES could be easily compromised. In fact, the Electronic Frontier Foundation once demonstrated that it took no more than 22 hours to break a DES key. The government then decided that it was necessary to find a better encryption standard with Nord VPN free @ Globalwatchonline.sl
