What does encryption do to data at rest and in transit?

Encryption is a crucial tool for securing data both at rest and in transit. When data is encrypted, it transforms the original information into a coded format that can only be accessed or interpreted by someone who possesses the appropriate decryption key. This process significantly enhances the security of sensitive information by ensuring that even if unauthorized individuals gain access to the stored data or intercepted communications, they would be unable to understand it without the decryption key.

The primary purpose of encryption in this context is to protect data from unauthorized access, making it an essential part of data security practices. This includes data stored on servers, databases, and storage devices (data at rest), as well as data being transmitted across networks (data in transit), such as during online transactions or email communications. By safeguarding the confidentiality and integrity of the information, encryption plays a vital role in maintaining trust and compliance with data protection regulations.
