Message-ID: <554CF6B9.7090807@web.de> Date: Fri, 08 May 2015 18:47:37 +0100 From: Demian Smith <demian.smith@....de> To: john-users@...ts.openwall.com Subject: Advise on best approach (truecrypt pw based on pdf file) Hi, I've recently lost my truecrypt PW and am thinking to approach the recovery with JtR but am unsure about the best approach to do so. So hopefully I could get a couple of pointers into the correct direction of setting it up. I know a couple of facts, which hopefully make it feasible in the first place: - I have created the password from a random page of a random book¹ - First letter MUST be capital - No numbers or diacritics, - Likely only I as second capital letter - No digits - Probably 5 -12 chars (I imagine it to be around 8, but that's guessing) At the moment I have tried creating a fake pot file from ¹ and creating a chr of it and then building a incremental rule: [Incremental:rc] File = $JOHN/rc.chr MinLen = 5 MaxLen = 12 CharCount = 36 And have now tried up till now 0g 7093116p 2:14:48:30 0g/s 31.37p/s 62.74c/s 62.74C/s toisooaaa..toisooatc However, I feel like wasting loads of work and time with tries I don't need (whitespaces - which I thought I had removed -, non-capital letters as first letter...) and I assume there must be a more efficient way of attempting my recovery. I am running 1.8.0.2-bleeding-jumbo_mpi+omp [linux-gnu 64-bit SSE4.1-autoconf] on a Intel(R) Core(TM) i5 CPU M 480 @ 2.67GHz So, can I please ask your advise on how to apply a decent statistical analysis on the txt of the book and/or prepare a proper incremental/external rule or, simply speaking, what's the best approach in your opinions? (¹ I have tried cat INFILE | sed -re 's/[?!.:]/\n/g' | sed -re 's/([A-Za-z])[A-Za-z]+[^A-Za-z]*/\1/g' > outfile on a txt version of the pdf and using "outfile" as a wordlist - no luck) Kind regards and thank you in advance, Demian
