NetNTLMv2 Empty Hash Checker (MIT License)

This tool was originally created because hashcat does not permit to crack empty hashes.

I hope it will be useful to you !

Usage

This tool only processes hashes in the Responder format. An example hashes.txt file is provided in this repository which represents a totovoid account with an empty password.

$ node index.js --help

Usage: netntlmv2-empty-checker [options] hashfile
Options:
  -h, --help         Show this help message and exit
  -o <file>          Output to file instead of stdout
  --full             Print full hash lines instead of only usernames
  -p, --password <pw>  Test this password instead of empty string

Use "-" as hashfile to read from stdin.
Use "./-" if you really want to read a file named "-".

$ node --openssl-legacy-provider index.js hashes.txt
totovoid
