Abstract
With files secured by encryption techniques, keys are often required to gain access to the secured files. Techniques for providing and using multiple levels of keystores for securing the keys are disclosed. The keystores store keys that are needed by users in order to access secured files. The different levels of keystores offer compromises between security and flexibility/ease of use.
