ssdeep is a fuzzy hashing program and library that is useful for finding almost identical files.
>From pkg/DESCR: "ssdeep is a program for computing context triggered piecewise hashes (CTPH). Also called fuzzy hashes, CTPH can match inputs that have homologies. 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. The package also includes a fuzzy hashing API, which is documented in the README file." Sample usage: $ ssdeep /bsd ssdeep,1.1--blocksize:hash:hash,filename 196608:0FEGkK3+KgZ50tiuWUcvExbAcLYZ3lbAn7YZqWE/j0yky8Q3oM3ocm7GAWJ:ZyUuUA7YEp,"/bsd" This URL shows more usage examples: http://ssdeep.sourceforge.net/usage.html#basic ok?
