What is the main purpose of data encryption?

The main purpose of data encryption is to secure sensitive information. Encryption transforms data into a coded format that can only be read by someone who has the correct decryption key. This ensures that sensitive information, such as personal data, financial records, and confidential communications, cannot be easily accessed by unauthorized users. By protecting information in this way, encryption plays a critical role in maintaining privacy and compliance with data protection regulations.

The other choices do not accurately reflect the purpose of encryption. Increasing data storage pertains to storage solutions and techniques rather than the encryption process itself. Enhancing internet speed is related to bandwidth and network optimization, which are not the primary focus of encryption. Simplifying data processing involves making data formats easier to manage or analyze, which is distinct from the goals of encryption that revolve around confidentiality and security.
