# ssdeep Fuzzy Hashing

&reftitle.intro;

ssdeep is a utility for creating and comparing fuzzy hashes or context-triggered piecewise hashing.

Fuzzy hashing can match signatures which have "...sequences of identical bytes in the same order, although bytes in between these sequences may be different in both content and length". ( ssdeep project page)

This extension provides functions for creating and comparing fuzzy hashes.
