How to retrieve Key Alias and Key Password for sig

Question

I have an android app currently published in Google Play which I update periodically. I follow the following process to sign the app before a new push:

Press right-mouse on the project, the 'Android tools' -> export signed application package Provide keystore password Sign your app Upload the apk file into Google Play Developer Console

Recently I have imported the project from Eclipse to Android Studio and continued working on Android Studio. Now I am planning to push a fix in the app. I have figured that I have this option to sign apk in android studio

Build -> Generate Signed apk ->

As per my understanding, for my android app I have to use the same key store and key store password which I used earlier to push updates into Google Play. Also here it's asking for Key Alias and Key Password. I don't remember the Key Alias and Key password(number 4 input in the image) while signing apk in Eclipse. Any suggestion what can I do now? If I already know my keystore and keystore password, is there an way to retrieve the key alias and alias key password?

Update: Now I can retrieve my key alias through keytool -list -v -keystore name.keystore command

Answer 1

Based on gkemp answer, On Windows, I found the keystore file path, password, key alias and key password in an earlier log report before I updated Android Studio.

From windows file explorer c:/Users/your pc name/.AndroidStudio1.4 (your android studio version)\system\log\idea.log.1 (or any old log number)

Then I searched for “android.injected.signing.store” and found this from an earlier date:

-Pandroid.injected.signing.store.file= path to your keystore 
-Pandroid.injected.signing.store.password=yourstorepassword
-Pandroid.injected.signing.key.alias=yourkeyalias
-Pandroid.injected.signing.key.password=yourkeypassword

Answer 2

To just restore the KEY ALIAS. Type the below command on terminal.

$ keytool -list -v -keystore <storekey>

It will give information starting,

Your keystore contains 2 entries...

You can look for the alias name there.

Answer 3

Just Open yourApp.jks file with Notepad you will find Keystore & Alias name there!!

You might like to try this password breaker.

I was using the Dictionary Attack method. It worked for me because there were only a few combinations to my password that I could think of.

how to retrieve keystore password

You cannot retrieve the password. If you forgot it, you are doomed.

how to retrieve key alias

$ keytool -list -v -keystore <store>

But you need keystore password for this first.

EDIT

What I don't remember is the 'Key Password'

No password can be restored. If you forgot key password for good then you are doomed too and there's no other way than trying harder to recall it. There's no password reset thing nor anything like that.

Be aware that if you forgot your password for good then you will issue no further updates to your app (docs):

Warning: Keep your keystore and private key in a safe and secure place, and ensure that you have secure backups of them. If you publish an app to Google Play and then lose the key with which you signed your app, you will not be able to publish any updates to your app, since you must always sign all versions of your app with the same key.
