Disk encryption, also known as full-disk encryption (FDE) or whole-disk encryption (WDE), is a technology that encrypts all data stored on a computer's hard drive or other storage devices. This encryption ensures that only authorized users can access the data, as it is rendered unreadable without the correct decryption key.

The process of disk encryption involves using cryptographic algorithms to scramble the data on the disk. When the computer is booted, the operating system or a specialized pre-boot authentication program prompts the user for a password or key. If the correct credentials are provided, the decryption key is revealed, allowing the system to decrypt and access the data. Without the correct key, the data remains encrypted and inaccessible.

Disk encryption is commonly used to protect sensitive information from unauthorized access in cases of theft or loss of the device. It is also employed in enterprise environments to comply with data privacy regulations and safeguard corporate data. Various software and hardware solutions offer disk encryption capabilities, with options ranging from operating system built-in features to third-party applications and dedicated hardware encryption chips. The strength and effectiveness of disk encryption depend on the chosen encryption algorithm, key management practices, and the overall security of the system.
