L0phtCrack was one of the original and greatest hacking and auditing tools of the 90's, essentially creating the modern LM/NTLM password auditing landscape. L0pht Heavy Industries - the creators of the tool - were instrumental in raising awareness of both the ease of cracking passwords as well the obviousness of how poorly people choose passwords.
For those of you who are struggling to find a way to convert PDF files into TXT files, here is a quick bash script. There are many alternatives out there, but none were reliable for me. You’ll need to have acroread and ghostscript installed for this to work.
mkdir ps txt
for f in $FILES
echo "Processing $f"
acroread -toPostScript $f ps/
g=`basename $f .pdf`
ps2txt ps/$g.ps > txt/$g.txt
You can also change the second to last line to read
ps2txt ps/$g.ps | grep -v "EXCLUDE" > txt/$g.txt
where EXCLUDE is a line that you want to exclude from each PDF. Please let me know if you have any problems.
