Abstract
A method begins by a distributed storage (DS) managing unit receiving an encryption key to store. The method continues by determining an encryption method and encrypting the encryption key with the determined encryption method to produce an encrypted key. The method continues by encoding and slicing the encrypted key to produce a set of data slices; and storing the set of data slices in DSN memory. A method to retrieve the stored encryption key begins with receiving a retrieve encryption key request from a requester and continues with retrieving an encrypted key and then determining a decryption method. The method continues by decrypting the encrypted key with the determined decryption method to produce the encryption key and sending the encryption key to the requestor to decrypt one or more portions of the encrypted data.
