How to retrieve Key Alias and Key Password for signed APK in android studio(migrated from Eclipse)

On the Mac, I found the keystore file path, password, key alias and key password in an earlier log report before I updated Android Studio.

I launched the Console utility and scrolled down to ~/Library/Logs -> AndroidStudioBeta ->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=/Users/myuserid/AndroidStudioProjects/keystore/keystore.jks, 
-Pandroid.injected.signing.store.password=mystorepassword, 
-Pandroid.injected.signing.key.alias=myandroidkey, 
-Pandroid.injected.signing.key.password=mykeypassword,

On Windows

you can find your lost key password in below path

Project\.gradle\2.14.1\taskArtifacts\taskArtifacts.bin or ..taskHistory\taskHistory.bin

open the file using appropriate tools e.g. NotePad++ and search with the part of the password that you remember. You will find it definitely. Else, try searching with this string "signingConfig.storePassword".

Note: I have experienced the same and i am able to find it. In case if you didn't find may be you cleared all the cache and temp files.

I finally could figure the issue out.

To get the Key Alias: I copied the keytool.exe and my keystore file into C:\Program Files\Java\jdk1.7.0_71\bin folder. Then from command prompt I wrote: keytool -list -v -keystore <name>.keystore It will also ask for keystore password then. Then it will show you the key alias and Certificate fingerprints and other info.

Then I again tried to Generate Signed Apk for the project, I provided keystore, keystore password, key alias and provided the same password. Then it asks for master password, I tried with the same and it failed. With the reset option I reset the master password here.

how to retrieve keystore password

You cannot retrieve the password. It is not stored in keystore file in any form so there's nothing to retrieved. If you forgot your password, then you are pretty much 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 or try some brute-force attempts as keytool won't throttle you there, so depending on your needs (and desperation) you can try that, but in general things do not look promising. There's also no password reset thing nor anything like that.

Be aware that if you forgot your password for good then you will not be able issue no further updates to your already published 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.

If you happen to be on MacOS and checked the "save password" box in Android Studio, you can recover the password from Keychain Access.

Launch Keychain Access from Applications/Utilities. Select password in Category, on the left panel. On the search box top right, type your Android app name or part of the app name. You will see the result line, if you had saved the password. Double click on it, check the show password checkbox, give your system password when asked, and it will show your keystore password.

You can find your keystore details without using password as following way.

Execute the command (keytool -list -keystore <path>) in command prompt

You can find the Keytool in java folder in my machine I could find form the following path

C:\Program Files (x86)\Java\jdk1.7.0_71\bin> keytool -list -keystore C:\<YourKeystore>.Keystore

Then it will ask you to enter the password, Here you don't need to enter the password instead of that press up arrow button and enter it. then the same details will be display with warning message as below.

Don't waste your time with all those solutions, they do not work anymore google managed to fix all those leaks and crypted the password on all those mentioned files. Just contact the google support, Create a new Keystore file and send it to them they will update it for your app.

You might like to try this password breaker.

http://maxcamillo.github.io/android-keystore-password-recover/index.html

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.

Android Studio 3.0 below working method: Find your old zipped project. If you have built the apk, you'll find the password in file:

Project\.gradle\2.14.1\taskArtifacts\taskArtifacts.bin

Pandroid.injected.signing.store.password=password

If you don't have zipped project, search your git repositories if you have .gradle folder pushed or not. Otherwise you'll have to recover files and search files by content "Pandroid.injected.signing.store.password".

Lost or compromised upload key? If you’ve lost your private upload key or it’s been compromised, you can create a new one, and then ask your account owner to contact support to reset the key. When contacting support, make sure your account owner attaches the upload_certificate.pem file.

After our support team registers the new upload key, you receive an email, and then you can update your keystores and register your key with API providers.

Important: Resetting your upload key doesn’t affect the app signing key that Google Play uses to re-sign APKs before delivering them to users.
