What is the purpose of encryption in data security?

Encryption plays a crucial role in data security by transforming data into a code to prevent unauthorized access, thereby safeguarding both its integrity and confidentiality. The primary purpose of encryption is to ensure that only authorized users can access and interpret sensitive information, such as personal identification, financial records, or confidential communications. By encrypting data, it becomes unreadable to anyone who does not possess the correct decryption key, thereby protecting it from potential breaches and unauthorized alterations.

Ensuring data integrity means that the information has not been altered in unauthorized ways during transmission or storage. Encryption also maintains confidentiality by ensuring that only those with the proper credentials can view the content, which is essential for compliance with regulations and maintaining trust with users. This dual focus on integrity and confidentiality is vital in a world where data breaches and cyber threats are increasingly common.
