## HashDB is a community-sourced library of hashing algorithms used in malware.
## New hash algorithms can be added here: https://github.com/OALabs/hashdb
##
## Updated for IDA 7.xx and Python 3
##
## To install:
## Copy script into plugins directory, i.e: C:\Program Files\<ida version>\plugins
##
## To run:
## Configure Settings:
## Edit->Plugins->HashDB
## click `Refresh Algorithms` to pull a list of hash algorithms
## select the hash algorithm you need from the drop-down
## OK
## Lookup Hash:
## Highlight constant in IDA disassembly or psuedocode view
## Right-click -> HashDB Lookup
## If a hash is found it will be added to an enum controlled in the settings
## Right-click on the constant again -> Enum -> Select new hash enum
