Claim Text:
1. A method for processing an encryption key within a portion of a distributed storage network (DSN), the method comprises: receiving an encryption key to store; determining an encryption method; encrypting the encryption key with the determined encryption method to produce an encrypted key; determining a pillar width of a DSN user storage vault as a parameter of a dispersed storage error coding function; encoding the encrypted key in accordance with the dispersed storage error coding function to produce a set of encoded encrypted key slices, wherein a number of encoded encrypted key slices in the set of encoded encrypted key slices is equal to the pillar width, wherein a decode threshold number of the encoded encrypted key slices of the set of encoded encrypted key slices is required to reconstruct the encrypted key; and storing in a distributed manner across the DSN user storage vault the set of encoded encrypted key slices in DSN memory.
