Package: dexofuzzy
Dexofuzzy: Dalvik EXecutable Opcode FuzzyhashDexofuzzy is a similarity digest hash for Android. It extracts Opcode Sequence from Dex file based on Ssdeep and generates hash that can be used for similarity comparison of Android App. Dexofuzzy created using Dex's opcode sequence can find similar apps by comparing hash.RequirementsDexofuzzy requires the following modules:ssdeep 3.3 or laterUsageusage: dexofuzzy [-h] [-f SAMPLE_FILENAME] [-d SAMPLE_DIRECTORY]
                 [-g N M][-s DEXOFUZZY DEXOFUZZY]
                 [-c CSV_FILENAME] [-j JSON_FILENAME]
