Every conversation with loved ones, employers and employees, and basically anyone who plays a role in your life is made easy with the help of digital communication. That is why securing your communications has become more crucial than ever.

In this rapidly evolving digital landscape, encryption is a powerful tool to shield your sensitive information from prying eyes.

Why does encryption matter in today's digital world?

Encryption is a form of secure lock box that protects your digital conversations and data. It transforms all your readable information into an unreadable format which is accessible only to those with the right decryption key.

In India, Internet users are crossing the 900 million mile marker and the threat of cyber-attacks and data breaches is growing exponentially. Cyber criminals are targeting individuals, businesses and even government institutions thus making it imperative to adopt powerful security measures.

You may have come across the term end-to-end encryption on WhatsApp or emails Without understanding the underlying meaning of these terms. So let us simplify what encryption means. Encryption ensures the following protocols:

1. The privacy protection under encryption software ensures that your personal messages, financial details and professional communications remain confidential.

2. Encrypted data is less vulnerable to tampering, thus making it easier to maintain data integrity.

3. Encryption provides a sense of security. Knowing that your sensitive information is secure allows you to interact online without the constant fear of being hacked by pryers and scammers.

Of course, this is not to say that Encryption can keep deep hackers at bay. However, it does a fairly good job of keeping your information private so that even the best hackers need stupendous skills and software to decrypt the outer layer of your information.

Types of encryption you should know

There are various types of encryptions that can help secure your data. Let us learn more about the most popular forms of encryption that you may come across in day-to-day life or may find useful:

1. End to end encryption (E2EE)

End-to-end encryption is the most popular form of encryption that you may have come across in various modes of communication. It ensures that only the sender and the recipient are privy to the contents of the communication. Several popular messaging platforms such as WhatsApp use E2EE to secure chats and calls. In India, where messaging apps are lifelines for both personal and professional communication End to end encryption is a vital form of maintaining privacy.

2. Symmetric encryption

The symmetric encryption method utilises a single key for both encryption and decryption. It is a fast and efficient means of securing your information and is commonly used for encrypting large amounts of data.

3. Asymmetric encryption

Asymmetric encryption is a form of employing a pair of keys that you can use to encrypt and decrypt your data. A public key is used to encrypt the information and a private key is used to decrypt the information by people who are privy to the data. This form of encryption is widely used to secure e-mail communication and digital signatures.

Based on the forms of communication and software that you use, you can find access to any of these types of encryption. It is always good to employ these means of encrypting your communications to keep your information secure and away from prying eyes. You can protect yourself further using cyber insurance to adequately conserve the data on your personal and professional servers, and file claims in cases of breach.

How to incorporate encryption in your daily life?

For businesses, Cyber attacks targeting Indian enterprises have surged in the last few years with ransomware, phishing and data breaches. Encrypting transactions and data handling instil confidence among your customers. Indian data protection laws, such as the proposed Data Protection Bill, emphasise secure data handling thus making encryption essential.
