The primary purpose of encryption is to make data unreadable without the proper key. This process converts information into a coded format that can only be deciphered by someone who possesses the correct decryption key. The intent behind encryption is to protect sensitive data from unauthorized access, ensuring confidentiality and integrity. In scenarios where data is transmitted over networks or stored in databases, encryption safeguards it against eavesdropping and theft, serving as a crucial defense mechanism in cybersecurity. By utilizing encryption, organizations can ensure that even if data is intercepted or accessed without permission, it cannot be interpreted without the necessary key. This method not only helps to secure personal and financial information but also complies with regulatory and legal standards for data protection. The other options describe processes or objectives that do not align with the inherent goal of encryption. Making data readable by everyone, ensuring efficient storage, or compressing data may serve different purposes but do not contribute to the foundational aspect of protecting data confidentiality, which is the essence of encryption.
