Generate SHA-1 for Flutter/React-Native/Android-Native app

I'm trying to generate a SHA-1 for a Flutter app, for Android studio to support Google Sign in, but I don't know how to do that, I saw some posts that indicate to run a command, but there I need a jks file I guess, and flutter doesn't create that.

Could someone help me?

TERMINAL

Go to the project folder in the terminal.

Mac keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Windows keytool -list -v -keystore "\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

Linux keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

GUI Android Studio.

1. Select android/app/build.gradle file and on the right top corner click "Open for Editing in Android Studio"

2. Open Gradle panel and double click on "SigninReport",

see https://stackoverflow.com/questions/52253196/android-studio-gradle-tab/62337288#62337288

3. That's it! If you use Firebase - add these 2 keys there. You should add both keys, otherwise, without the release key, Google login will not work on the devices.

This is the easiest way-

1. Open Android Studio

2. Open Project

3. Reveal android folder

4. Right click "gradlew" file and select Open in Terminal -

5. Go to the terminal view and paste: gradlew signingReport

(edit based on Venkat D. suggestion below: on unix-based systems like mac, you need to specify the current directory like this- ./gradlew signingReport)

6. Press enter and scroll to "Variant: debug" to get the SHA1 key

7. Copy and use wherever you need it, Good Luck!

You won't find a gradle window view in flutter project, so here is a solution for that.. In command prompt navigate to bin folder of jdk and run this command

keytool -list -v -keystore "C:\Users\yourusernamehere\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

change user name in path

I partially agree with Rishab answer, but what we can do is

and this approach works with all flutter/React-native/Android ....

Navigate to Android folder inside project, there is gradlew file. so we can use this like :

gradlew signingReport 

in Mac

./gradlew signingReport

in my case i use it like :

D:\flutter\flutter_app\android>gradlew signingReport

Project Architecture is :

so if you are using an android studio or VS code it's work both of them

=> Open Terminal

=> cd android

=> signingReport

and the final output like this as given in the image below choice your SSH key in at the place of here is your SSH key

in the above output, image is shown in dummy data I change some of the fields just because of security purpose

Edit: for mac

./gradlew signingReport

run this commend it work any where

in android folder

./gradlew signingReport

for example

PS E:\flutterProject\flutter_app\android> ./gradlew signingReport

some time you not need add ./ just

> gradlew signingReport

this work for android studio and cmd and commond prome

Simple and easy:

cd android && gradlew signinReport

For Android Studio 4.2 and Flutter 2.2

Windows:

Open your project open android > gradlew > right click on it and click open in terminal

Like below:

My Project Directory: D:\AndroidStudioProjects\WowTalentNew\android>gradlew

open this in terminal.

After build finished execute this

D:\AndroidStudioProjects\YourProjectDirectory\android>gradlew signinReport

After that you will see the SHA keys

in Linux instead of just type gradlew we write ./gradlew to build. and to get SHA-1 we write: Terminal> ./gradlew signinReport and we could just build and get SHA-1 key with just one command: Terminal> ./gradlew signinReport

I hope it clears everything, happy coding!

you can do the same on VSCode, open the folder that contain gradlew for linux and gradlew.bat for windows and run ./gradlew signingReport for linux and run gradlew signingReport for windows

1-write those two commands in android studio's or vscode terminal:

cd android
gradlew signingReport

2-wait a bit then scroll up.

Check this Authenticating Your Client  |  Google APIs for Android

To get the debug certificate fingerprint:

for Mac or Linux

keytool -list -v \ -alias androiddebugkey -keystore ~/.android/debug.keystore

for Windows

keytool -list -v \ -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

The default password for the debug keystore is android.

The keytool then prints the fingerprint to the terminal.

1. First Methord just run the below command

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

2. Second Methord

1. Left side open the android folder not the whole project in android studio.

2. Right Side open the file android/app/Tasks/anroid/signingReport

Final this process will take some time and it might be of 5-10 minutes so be patient

To generate SHA-1 for a Flutter

1. Locate your android directory inside the console

E:\<appname>\android>

2. After locating to the android folder run this command

./gradlew signingReport

If this won't work and opens a daemon terminal

1. Type signingReport in daemon terminal

daemon> signingReport

> This would be taking a bit long time to generate your first SHA-1 as it > would be checking for all the firebase dependencies and after that > over it generate the SHA-1

Method 1

• Make sure java is installed in your system.

Method 2

• Using Command-line change your username and run the below command

keytool -list -v -alias androiddebugkey -keystore C:\Users\YOURUSERNAME\.android\debug.keystore

• the default password is android

go to the android folder in terminal

cd android .\gradlew signingReport

it will generate your SHA1 and SHA256 for you

You can generate it even from terminal. Following is for the release mode:

keytool -list -v -keystore keystore_location -alias alias_name

example :

keytool -list -v -keystore /home/user/key.jks -alias alias_name

First, check which Keystore is being used by your project in

Then use the below command

 keytool -list -v -alias mstoreappsemoAlias -keystore  fluxstorepro/android/app/mstoresemoFile.keystore    

and if you want to generate a hash key for Facebook then use the below command

 keytool -exportcert -alias mstoreappsemoAlias -keystore fluxstorepro/android/app/mstoresemoFile.keystore | openssl sha1 -binary | openssl base64

If you have the keystore file, then run keytool -list -v -keystore fileName.jks -alias upload -storepass password -keypass password at the keystore file location...

> Flutter Project Using MAC & VS Code

• Step One
  Go To the Android Gradle Properties and add this line

https://services.gradle.org/distributions/gradle-6.3-all.zip

• Step Two Open the Terminal at android Folder of your Projects . then in the terminal type

.\gradlew signinReport

you will get the signing report Like this :

To get generate a SHA-1 key

in the terminal type cd android and change the path then type ./gradlew signingReport

try writing this in Terminal - For Windows > cd android

> gradlew signingReport

for linux:

1. if you are using vscode you can right-click on gradlew->copypath (in my case: /home/alif/Documents/project/flutter/fit_app/android/gradlew)
2. open your terminal and paste it, don't forget to delete /gradlew
3. type .../android gradlew signinReport and hit enter

good luck!

I found that I needed to check the fingerprint in Google Play Console, since I have Google Play managed app signing.

The ones provided by gradlew did not work for me.

Note that you can put both in Firebase, but you only need one. I just added the SHA1 and Google Sign In began working.

Personally, I went to the terminal then navigated to C:\Program Files\Java\jdk-14.0.2\bin (navigate to your java bin folder).

Next, I ran this command and it worked: keytool -list -v -keystore "%USERPROFILE%.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

You can use one line in terminal

echo y | keytool -genkeypair -dname "cn=Chris, ou=JavaSoft, o=Sun, c=US" -alias business -keypass kpi135 -keystore /working/android.keystore -storepass ab987c -validity 20000

• dname is a unique identifier for the application in the .keystore
• cn the full name of the person or organization that generates the .keystore
• ou Organizational Unit that creates the project, its a subdivision of the Organization that creates it. Ex. android.google.com
• o Organization owner of the whole project. Its a higher scope than ou. Ex.: google.com
• c The country short code. Ex: For United States is "US"
• alias Identifier of the app as an single entity inside the .keystore (it can have many)
• keypass Password for protecting that specific alias.
• keystore Path where the .keystore file shall be created (the standard extension is actually .ks)
• storepass Password for protecting the whole .keystore content.
• validity Amout of days the app will be valid with this .keystore

> gradlew signingReport

Use this command on Terminal which you can find in bottom left corner.
