You should. > Even if incremental now runs what you intended, it could take a LONG time (as in years) to hit the correct phrase. What if you use that wordlist you produced and instead of making a fake pot file, use it directly as a wordlist in a crack? If it's the correct book I reckon you'd crack your password in no time, no? I should have, indeed - I just did, but no luck. Potentially due to a typo or, more likely, a phrase compiled out of only a partial sentence in the book... I was hoping in the beginning it would crack with a word list, but it looks like I am out of luck in this regard... >> It looks to me you should upgrade to latest version from GitHub.

I think MPI is there from my first autoconfig and only for hashes that don't support OMP (in case I ever would need it). I run john with an alias: alias john='OMP_NUM_THREADS=4 ~/.bin/JtR/run/john' My benachmark looks like this (with the latest bleeding from github which I downloaded and made in the meantime) initUnicode(UNICODE, ASCII/ASCII) ASCII -> ASCII -> ASCII Will run 4 OpenMP threads Benchmarking: tc_aes_xts, TrueCrypt AES256_XTS [SHA512 128/128 SSE4.1 2x /RIPEMD160/WHIRLPOOL]...

(I ran the benachmark with the older version of John and boy is there a difference) > Also, when you resume the job, copy the inital lines output when job starts and report them too; Is it loading two "hashes"? Shouldn't it be just one? It does load 2 hashes alright, not sure what the reason would be, though? version 188.8.131.52-jumbo-1-bleeding_omp [linux-gnu 64-bit SSE4.1-autoconf] >Loaded 2 password hashes with 2 different salts (tc_ripemd160, TrueCrypt AES256_XTS >[RIPEMD160 32/64]) >Will run 4 OpenMP threads >Press 'q' or Ctrl-C to abort, almost any other key for status >0g 3178604p 0:19:58:10 0g/s 44.21p/s 88.42c/s 88.42C/s AioseaaU Would it be better to double check the hash file and maybe create it anew? Or is it a mal configuration of john.conf ? Again, thank you so much guys for your help and support! Demian
