hashcat/tools/recursivefiles2sha256sum.pl

#!/usr/bin/env perl

##
## This script was created to be used in conjunction with Hashcat mode 29700 (Keepass in keyfile only mode).
## This can be useful if you have a partition and forgot which of the files was used as the keyfile.
## 
## Example use (if your target drive is mounted to /mnt/sda1 and (optionally) another one to /mnt/sda2):
##
## $ perl recursivefiles2sha256sum /mnt/sda1 /mnt/sda2 > wordlist.dict
## $ ./hashcat kdbxdb.hash wordlist.dict
##
## Note that the redirection operator > also works on Windows cmd.exe.
## To run perl in Windows use strawberry perl
