A system for key storage and recovery includes an interface and a processor. The interface is configured to receive an indication to create a set of recovery encryption key shares. The processor is configured to receive a selection of one or more trusted entities from one or more categories; create a set of recovery encryption key shares based at least in part on one or more recovery encryption keys; and for a trusted entity of the trusted entities: 1) determine a trusted entity public key associated with the trusted entity; encrypt a recovery encryption key share of the set of recovery encryption key shares with the trusted entity public key to generate a trusted entity encrypted recovery encryption key share; and provide the trusted entity encrypted recovery encryption key share to the trusted entity.
