It also provides a library (libfuzzy) to generate/compare fuzzy hashes.
There is a free version of this paper available through the Digital Forensic Research Workshop conference,įree version of Identifying almost identical files using context triggered piecewise hashing. Identifying almost identical files using context triggered piecewise hashing from the journal Digital Investigation. Such inputs have sequences of identical bytes in the same order, although bytes in between these sequences may be different in both content and length.Ī complete explanation of CTPH can be found in Ssdeep is a program for computing context triggered piecewise hashes (CTPH).Īlso called fuzzy hashes, CTPH can match inputs that have homologies.
