1. A method for use in a pre-data manipulator of a computing device, the method comprising: determining when a data slice of a dispersed storage network (DSN) is to be refreshed; when the data slice of a dispersed storage network is to be refreshed, generating a data segment corresponding to the data slice based on a plurality of related slices of the dispersed storage network; combining the data segment with a sentinel value to generate a combined data segment; encrypting the combined data segment; calculating a digest of the encrypted combined data segment; encrypting an encryption key using the digest to produce a masked key; appending the masked key to the encrypted combined data segment to generate an encrypted package; and transmitting at least a portion of the encrypted package to a storage unit of the DSN.
