Data Encryption

Data encryption is a security technique that converts readable information, referred to as plaintext, into an unreadable format known as ciphertext. This transformation employs an encryption algorithm along with a key, allowing only those with the correct decryption key to retrieve the original data. Its main goal is to maintain the confidentiality of digital information, whether it is stored on a computer or transmitted over a network.

This method is fundamental to contemporary cybersecurity, protecting sensitive data from unauthorized access. It secures information both when it is stored on devices and while it is being transmitted across networks. This process is essential for preserving data confidentiality, ensuring compliance with regulations, and reducing the financial and reputational risks associated with potential data breaches.

Data encryption techniques are mainly divided into two primary categories based on their use of cryptographic keys. These categories, symmetric and asymmetric encryption, are essential to modern data security, each featuring unique mechanisms and applications.

Although data encryption and data masking both aim to safeguard sensitive information, they have different functions and operate in distinct ways.

A variety of algorithms underpin modern data security, each possessing specific traits. These mathematical methods are responsible for encoding and decoding data, ensuring its confidentiality and integrity.
