pw-inspector1

A tool to reduce the password list

Usage

pw-inspector [-i FILE] [-o FILE] [-m MINLEN] [-M MAXLEN] [-c MINSETS] -l -u -n -p -s

Overview

PW-Inspector reads passwords in and prints those which meet the requirements. The return code is the number of valid passwords found, 0 if none was found. Use for security: check passwords, if 0 is returned, reject password choice. Use for hacking: trim your dictionary file to the pw requirements of the target. Usage only allowed for legal purposes.
