What is the primary purpose of data encryption?

The primary purpose of data encryption is to protect sensitive information from unauthorized access. Encryption converts data into a coded format, which can only be deciphered back into its original form by those who possess the correct decryption key. This process is crucial in safeguarding confidential data, such as personal information, financial records, and proprietary business data, from cyber threats and data breaches.

Understanding the importance of encryption is vital in today’s digital landscape, where data breaches can lead to significant financial losses and reputational damage. Unlike the other options, which either imply a lack of security or focus on performance and cost, the core function of encryption is centered on securing data and ensuring that only authorized individuals can access it.
