The Different Types of Data Encryption and Why You Need Them

One of the biggest concerns in today’s digital world is online security, since more and more hackers keep popping up around every corner looking to steal or misuse sensitive information. It is something that scares many individuals using various online apps that require their personal information, especially when they are purchasing products online and need to provide their credit card details.

However, businesses of all sizes are those most targeted by hackers, since not only can they steal their customer information, but also gain access to email correspondence and various other business communications, as well as key website data and a lot of other information that can cost organizations quite a lot of money, not to mention their reputation.

In order to safeguard your data and make sure that it is protected at all times, even if a potential hacker does manage to gain access to it, you need to harness the power of encryption. Why do you need encryption? Because when you encrypt your data, you make it unreadable until a proper decryption key is used. That way, no prying eyes can ever read and misuse your data, and you can always keep it safe and secure.

With that in mind, take a look at the best encryption algorithms that you can use.


The Advanced Encryption Standard (AES) is considered the best symmetric encryption algorithm. It is a block cipher that has three keys: 128-bit, 192-bit and 156-bit. Being a block cipher, it is able to encrypt data by blocks rather than by bits. It uses 128-bit block size and encrypts blocks in rounds – 10 rounds for 128-bit key, 12 for 192-bit key and 14 for 156-bit key.

Since it is symmetric, meaning the key for decryption is not public, but needs to be shared with individuals in order for them to access the encrypted data, it is extremely secure.


3DES, or Triple DES, was created to replace the Data Encryption Standard (DES) algorithm, which used to be the standard until hackers learned how to crack it. 3DES is a symmetric block cipher that uses three individual 56-bit encryption keys, which essentially turns a 56-bit key into a 168-bit key.

However, this makes it slower than other encryption algorithms and, since it encrypts short blocks, it is very easy to decrypt data. Block sizes are 64 bits and there are 48 DES-equivalent encryption rounds.


RSA (Rivest–Shamir–Adleman) is an asymmetric encryption algorithm that uses a public-key cryptography for encrypting and decrypting data sent online. By using an RSA algorithm, you can safely share data over an insecure network and effectively protect it from potential hackers.

RSA uses two different keys, one public for encryption and one private for decryption. Mostly used RSA encryption keys are 1024-bit key and 2048-bit key, but there are 3070-bit and 4096-bit keys as well. These key sizes make encryption pretty slow, but also much more secure.


Blowfish is a symmetric encryption algorithm that was designed back in 1993 and still has not been defeated. It is yet another one created for replacing DES and it is a very flexible type of data encryption with a wide variety of use, such as for payment security in ecommerce and in numerous tools for managing and protecting passwords.

Blowfish is a block cipher that uses encryption keys varying from 32 bits up to 448 bits and splits data into 64-bit blocks in order to encrypt them. It encrypts each and every block individually in 16 rounds, regardless of the key size.


Twofish is Blowfish’s successor that is not patented and free for public use. It is a symmetric block cipher that uses 128-bit, 192-bit and 156-bit keys. It encrypts data in blocks of 128 bits in 16 rounds, regardless of the key size.

Knowing every option that you can choose from when it comes to data encryption and fully understanding them can greatly help you protect your data and keep it away from prying eyes. Data encryption is definitely a must, so make sure you find the best and most reliable software for data encryption that not only will safeguard all your personal and sensitive information, but also provide you with much-needed peace of mind.
