Abstract
Systems, methods, and other embodiments associated with the recovery of a lost site key value used in encryption are described. In one embodiment, site key recovery logic is configured to analyze an encrypted data item to identify a bin number and a hash table index within a header of the encrypted data item. The bin number is derived from a first portion of the site key value and the hash table index is derived from the site key value. The site key value includes at least the first portion and a second portion. A bin recovery process is performed on the bin number to recover the first portion. A filter matching process is performed using the first portion and a site key filter to recover the second portion. An index matching process is performed using the second portion and the hash table index to recover the site key value.
