In a world where cybercrimes are on the rise, knowing that there is something that you can do to protect your data can be relieving. One of the easiest ways to protect your data is through the use of the encryption process.

Encryption is a process that transforms information into codes that the authorized reader can only understand. The original text in its readable form is known as plaintext. After it is coded, it becomes encrypted data which is also known as ciphertext. When an authorized reader turns the ciphertext into its original form again, we can say that it has been deciphered.

Importance of data encryption


One primary importance of data encryption is the protection of sensitive data. Authentication helps the user to protect his data in a world where fraudulent websites flood the internet. Data protection is enabled as only the intended user is given access to the shared information. Also, authentication helps in verifying the origin of a message.


Encryption also ensures the confidentiality of sensitive data. When a message is encrypted, no one can decipher the message, apart from the intended recipient.


Another importance of encryption is that it helps protect data from breaches, whether the data is in transit or at rest. Also, encryption helps protect data against malicious activities while allowing parties to communicate without the fear of the information being leaked.

Main types of data encryption techniques

I. Symmetric encryption

The main advantage of symmetric encryption is that it is the simplest form of data encryption. In symmetric encryption, only one key is required to encrypt and decipher the information. It is mainly used to protect data at rest, and a 'key' is shared between the parties involved to access the data.

Examples of symmetric processes include; Data Encryption Standard (DES), Advanced Encryption Standard (AES), and Triple DES.

II. Asymmetric encryption

The most recent method of data encryption is asymmetrical encryption. It is mainly used when data is in transit. This method usually uses two keys (public and private) that are mathematically linked but not identical.

While the public key is used to encrypt information and is available to anyone who would wish to send you a message, the private key is only held by the recipient and is used to decipher the information received.

Examples of asymmetric processes include: Rivet-Shamir-Adelman (RSA), and Digital Signature Algorithm (DSA).

To further enhance your data's security, you can also download a VPN. VPNs work towards encrypting your internet traffic by disguising your identity online. It also hides your IP address, making it difficult for third parties to track your online activities.


Data encryption is a safe and affordable way to protect your data from third parties. Whether you choose symmetric, asymmetric, or hashing, this is a significant step towards ensuring that your data is safe.
