Need for an encryption software and how to use it

Encryption – a never aging process:

While IT security departments focus on making the environment even more safe (protecting your physical assets), it is easy to say that encryption protects the data that lives on and between those assets. Till date, encryption is considered as a top-notch option for security that has no loose ends. Know why? It is because even if a hacker is too tech-savvy and is able to get access to your data, it would be a fruitless attempt as your data would be in an unreadable form.

How does it work?

The process of encryption is connected with the ancient art of cryptography. It uses algorithms and computers to convert plain text into an unreadable form. An encryption key is (under your possession) is used to decrypt the protected data. Make sure you by all means are the only one having knowledge about that key and that you maintain its confidentiality. PCs are well able to break the encrypted code by making random guesses of the encrypted key, but in case of some sophisticated algorithms, (similar to an elliptic curvealgorithm), this could be a hefty, prolong process.

For example, if you want to encrypt a sentence, it would look like this:


You have the ability to share the key separately, send that encrypted message to some and the receiver with the help of the key would be able to read the original sentence.

In case if you want to send an encrypted email, only the individual having the encryption key would be able to see or read it. While shopping online if you are using an encrypted connection, you wouldn’t have to worry about losing your credit card information from hackers, prying eyes and more.

But also note that encryption can also be used for bad reasons as well. The attacks of ransomware are becoming way too common also known as DOS (denial of service) which uses encryption software prevents users from accessing their systems unless they pay a certain fee.

Encrypting data in transit vs data at rest:

While encrypting our data, we either go for data:

At rest: Data stored in databases, computer hard drives, the cloud or even mobile devices

In transit:Moving via email, through browsers, other web connections and in apps.

The solid method of achieving encryption is done by the following methods:

FDE (Full disk encryption): The basic method of protecting storage drives and the at-rest data on them. Whenever you save a file to the disk, it would be encrypted automatically. There are other moderate methods of encryption as well like volume encryption, file folder encryption etc.

File encryption:

A method to protect data at-rest on a file by file process. This helps in making sure your data isn’t intercepted easily. Although this isn’t an automated process, but is useful as data will remain in encrypted form even if it has left its place of origin.

E2E (End-to-end encryption):

 The concept of E2E is that it prevents all the threats on the communication chain i.e. the middle and the both extreme receiving ends. At first, E2E was a rare option not available to the masses but now, every common user is using it whether known to that fact or not. For example, WhatsApp, Facebook etc. all are letting their users avail this option.

Pre-encrypting data (synced with cloud):

A lot of software are readily available that can pre-encrypt data before it gets to the cloud (making it useless or unreadable by anyone who may have hacking ability).

What you missed?

The demand for the best all-rounder encryption software is rising at a deadly pace and the reasons behind such trends is quite familiar to the masses. Our advice would be simply revolve around the fact that encryption programs and security tools are the only hope for us to use and stay away from those unwanted malwares and spywares as the long-lost anti-viruses & firewalls are history.
