Usage

ethcracker -pk ~/test/pk.txt -t ~/test/templates.txt

-pk path to the private key file
-t  path to the template file
-l  path to the file with all the possible variants (every line has one variant) If -l is specified, -t is ignored
-presale  for cracking prelase JSON file
-threads Number of threads
-v Verbosity ( 0, 1, 2 )
-start_from Skip first N combinations
-keep_order Keep the order of the lines ( no permutations )
-re Report every N-th combination
-dump path Just dump all the variants into text file
-min_len Minimum password length
-max_len Maximum password length

Template file format

Every line contains the possible variants of the substring. For example file:

a1 a2 a3
b

will generate all those combinations

a1
a2
a3
b
a1b
ba1
a2b
ba2
a3b
ba3

Note: you can use \s to specify white space. ( "a\sb" means "a b" )

Template line flags

You can also specify some keys for every line.

~a always use some value from this string
~c Try both: capitalized and not-capitalized versions of all words. 

For example the template file

a 
~ac test

will generate all those combinations

test
Test
atest
aTest
testa
Testa
