What does encryption do?

Encryption is a vital cybersecurity measure that transforms data into a coded format, making it unreadable to unauthorized users. This process involves using algorithms to convert readable data into a format that can only be reverted back to its original state with the correct decryption key. The primary purpose of encryption is to ensure confidentiality and protect sensitive information from being accessed by individuals or systems that do not have permission to view it.

This function of encryption is fundamental in various contexts, such as protecting personal information, securing communications over the internet, and safeguarding data stored on devices. By ensuring that only authorized parties can access the original data, encryption plays a critical role in maintaining privacy and security in an increasingly digital world.
