Encryption can be defined as “translating data into a secret code”. This is the best way to keep your data safe. In order to access or read data from an encrypted file, you must have a secret key, or more simply, a password, to help you decrypt the file. For security algorithms, unencrypted data is known as plain text, while encrypted data is known as cipher text.

The data in encrypted files is stored in complex code that will be difficult to crack within a reasonable period of time. Hence, encryption is considered one of the best ways to protect personal or business data. For any corporate information, including medical, financial or legal information, security is extremely important.

Leaving unencrypted data in a cloud storage like Google Drive, DropBox or OneDrive, or on your personal computer is like leaving the doors open. Once attackers find out that your data is not encrypted, it becomes easy to target it.

When uploading your data to the cloud or storing it on the system, you should try to protect it with encryption. This applies to both personal and organizational nature.

The benefits of encryption

Data encryption technologies are widely available, which are implemented using several cryptographic algorithms. There are several benefits.

Data Integrity – Enhance data protection and information integrity. However, encryption alone cannot provide integrity, but by protecting the required data, it can keep the data safe from a hacker, which can be used by enterprises when making business decisions.

Privacy Protection – Data on your phone, computer, or in the cloud can contain sensitive information. Hackers can access and use your personal data from your device and use it in unauthorized ways, where data encryption can be proven to guarantee the confidentiality of your data.

Increase Trust – Many businesses may not need data protection, but to show their customers how serious they are about their customers’ security, they use encryption. Using data encryption can increase customer confidence as they learn how serious you take data privacy.

Working remotely – many companies prefer remote workers. Employees are expected to use encrypted devices. However, in the case of remote work, the risk of data breaches is quite high. Data encryption can ensure complete security of information.

Next, let’s take a look at some of the best encryption software available for Windows and macOS.
