HashTypeCybOX Common Schema

The HashType type is intended to characterize hash values.


Field Name Type Description
Type0..1 ControlledVocabularyStringType

The Type field utilizes a standardized controlled vocabulary to capture the type of hash used in the Simple_Hash_Value or Fuzzy_Hash_Value elements.

This field is implemented through the xsi:type controlled vocabulary extension mechanism. The default vocabulary type is HashNameVocab in the http://cybox.mitre.org/default_vocabularies-2 namespace. This type is defined in the cybox_default_vocabularies.xsd file or at the URL http://cybox.mitre.org/XMLSchema/default_vocabularies/2.0.1/cybox_default_vocabularies.xsd.

Users may also define their own vocabulary using the type extension mechanism (by specifying a vocabulary name and/or reference using the vocab_name and vocab_reference attributes, respectively) or simply use this as a string field.

Simple_Hash_Value0..1 SimpleHashValueType

The Simple_Hash_Value field specifies a single result value of a basic cryptograhic hash function outputting a single hexbinary hash value.

Fuzzy_Hash_Value0..1 FuzzyHashValueType

The Fuzzy_Hash_Value field specifies a single result value of a cryptograhic fuzzy hash function outputting a single complex string based hash value. (e.g. SSDEEP's Block1hash:Block2hash format).

Fuzzy_Hash_Structure0..n FuzzyHashStructureType

The Fuzzy_Hash_Structure field is optional and enables the characterization of the key internal components of a fuzzy hash calculation with a given block size.
