Abstract: In an example, a system may include an object store for storing objects, wherein each object is identified by an object signature generated according to a first cryptographic function, wherein the objects stored in the object store exhibit a hierarchical relationship from a root object. The system may receive a second cryptographic function for the object store, receive an I/O request affecting an object in the object store, encode the affected object according to the second cryptographic function, and persist the affected object alongside other objects in the object store encoded according to the first cryptographic function.
