Abstract
Techniques are disclosed for managing encrypted data stored in one or more blocks of a first data structure. One embodiment presented herein includes a computer-implemented method, which includes retrieving the encrypted data from the one or more blocks. The method further includes placing the encrypted data in a container object. The method further includes applying an encryption technique to the container object to generate an encrypted container object and a key. The method further includes generating a second data structure. A first block of the second data structure may include either the encrypted container object or information related to the encrypted container object.
