Lost Keystore password
android, apk
Solution
As @CRUSADER said, Android Keystore Password Recovery might work for you. I could retrieve my password with it. Here is how to do that. I was on Windows 7.
Run the following command,
java -jar AndroidKeystoreBrute_v1.05.jar
Then you will get the following guide,
AndroidKeystorePasswordRecoveryTool by M@xiking
Version 1.03
There are 3 Methods to recover the key for your Keystore:
1: simply bruteforce - good luck
2: dictionary attack - your password has to be in the dictionary
3: smart dictionary attack - you specify a dictionary with regular pieces you use in your passwords. Numbers are automat
icly added and first letter will tested uppercase and lowercase
args:
-m <1..3> Method
-k <path> path to your keystore
-d <path> dictionary (for method 2 and 3)
-w saves the certificate in a new Keystore with same passwort than key
-start <String> sets start String of the word (for method 1)
-p use common replacements like '@' for 'a'(for method 3) WARNING - very slow!!
-h prints this helpscreen
Max memory: 247M
I've used method 2 because I had some guess of my password. I typed the following command,
java -jar AndroidKeystoreBrute_v1.05.jar -m 2 -k android.keystore -d dict.txt
In case you might wonder, my dict.txt was something like this,
gussedpassword1
gussedpassword2
gussedpassword3
I could successfully retrieve my password and alias.
