Package emissary.kff

Understanding data through hashing. Provides the framework to run one or a chain of file filters that can identify data by hash sum, either SHA-1, MD5 or some other algorithm. There are implementations that read from custom mmap'ed memory regions, implementations that read from files and from Databases via JDBC.

Class Summary

Class	Description
ChecksumResults	This class is a value object to store the results of both a CRC32 and a message digest computation.
EditDistance	A java port of the ssdeep code for "fuzzy hashing". http://ssdeep.sourceforge.net There are a number of ports out there that all look basically the same.
KffChain	Keep a list of hash algorithm names and compute them and compare the results to the ordered chain of KFF filter when data is submitted.
KffChainLoader	Loads a chain of file filter specified by the configuration subsystem Expects to find a configuration file with a list containing class names that implement known or dupe type filter working either against file stores of hashes or database tables of hashes, plus a list of the algorithms that are desired to use.
KffDataObjectHandler	A helpful class to set and evaluate the KFF details of a BaseDataObject
KffFile	KffFile provides access to the known file filter data.
KffMemcached	KffMemcached checks Emissary hashes against a set of external memcached servers.
KffQuincyFile	KffQuincyFile compares files against the Quincy KFF dataset.
KffResult	Provide results of a KFF check including the details of the hash or cryptographic sum or sums that were used.
SpamSumSignature	A java port of the ssdeep code for "fuzzy hashing". http://ssdeep.sourceforge.net There are a number of ports out there that all look basically the same.
Ssdeep	A java port of the ssdeep code for "fuzzy hashing". http://ssdeep.sourceforge.net There are a number of ports out there that all look basically the same.
