Abstract: Examples include a system comprising a processing resource and a memory resource. Examples include a cryptography engine arranged in-line with the processing resource and the memory resource. The cryptography engine is to selectively decrypt data during read accesses of the memory resource by the processing resource.

Abstract: Examples of a system and method for securing data on a computing device are described herein. One or more cryptographic operations are executed on at least a portion of data stored in a memory module of the computing device in response to a change of operational state of the system from a first operational state to a second operational state.

Abstract: An example non-transitory computer-readable medium includes instructions that, when executed by a processor, cause the processor to receive a request for data. The instructions also cause the processor to determine a region containing the data based on the metadata. The instructions cause the processor to traverse a tree in the metadata to determine key generation information relating a decryption key for the region to a root key.
