If you forgot your password for Ethereum private key or presale file, but think you still remember the list of possible substrings from wich you constracted the password, then try this progam to routinly go through all the possible combinations and find the working password.
PLEASE DO NOT TRUST ANYONE TO COMPILE THE PROGRAM FOR YOU. ALWAYS USE THE SOURCE CODE DOWNLOADED FROM THE GITHUB. THIS WAY YOU CAN BE SURE, THE PROGRAM DOES NOT HAVE ANY MALICIOUS CODE !!!
https://gitter.im/lexansoft/ethcracker
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 ( you can specify N as percentage. F.e. : 30% )
-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
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" )
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
Install Go Language
git clone https://github.com/lexansoft/ethcracker
cd ethcracker
go get github.com/ethereum/go-ethereum
go get github.com/pborman/uuid
go get golang.org/x/crypto/pbkdf2

On windwos you need to install the Chocolatey: https://chocolatey.org
Then install git, golang and mingw
choco install git
choco install golang
choco install mingw
After that make all the steps from the Installing section.
If you stored your keys in the encrypted mac DMG image and forgot the password, do this:
dump all the possible variants of your password into a file
go run src/ethcracker.go ... -dump ~/v.txt
Use dmg_pass.bash script to try all the variants form v.txt
./dmg_pass.bash v.txt your.dmg
or
./dmg_pass.bash v.txt your.dmg N -- to skipp first N lines
