How to go about a password you know has 3 - 5 more or less known words?

[philsmd]

you could just use --stdout -a 1 or combinator.bin or combinator3.bin to generate a dictionary file.

you could for instance start with a list of 2 words combinated together and with -a 1 add the 3rd one (2 + 1 = 3):

Code:

hashcat -m 13000 -a 1 -w 3 hash.txt two_words.txt one_word.txt

3 words and add one (3 + 1 = 4):

Code:

hashcat -m 13000 -a 1 -w 3 hash.txt three_words.txt one_word.txt

or (2 + 2 = 4):

Code:

hashcat -m 13000 -a 1 -w 3 hash.txt two_words.txt two_words.txt

and finally 5 words (3 + 2 = 5):

Code:

hashcat -m 13000 -a 1 -w 3 hash.txt three_words.txt two_words.txt

of course you need to generate all those files first and it's of course only possible/feasible to do so if the number of words is very low (because combining 5 words each one with each other will grow exponentially with the number of words):

Code:

hashcat --stdout -a 1 -o two_words.txt one_word.txt one_word.txt

or:

Code:

combinator one_word.txt one_word.txt > two_words.txt

or for 3:

Code:

combinator3 one_word.txt one_word.txt one_word.txt  > three_words.txt

etc etc
