How can I find and run the keytool
I am reading an development guide of Facebook Developers at here
It says that I must use keytool to export the si开发者_高级运维gnature for my app such as:
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
I do not know how to find the keytool in order to run it. I tried to open a Windows command prompt and paste the above command, but it did not work.
I found a solution by myself as below quote. It works fine.
"C:\Program Files\Java\jdk1.6.0_26\bin\keytool.exe" -exportcert -alias
> sociallisting -keystore "D:\keystore\SocialListing" |
> "C:\cygwin\bin\openssl.exe" sha1 -binary | "C:\cygwin\bin\openssl.exe"
> base64
Simply enter these into Windows command prompt.
cd C:\Program Files\Java\jdk1.7.0_09\bin
keytool -exportcert -alias androiddebugkey -keystore "C:\Users\userName\.android\debug.keystore" -list -v
The base password is android
You will be presented with the MD5
, SHA1
, and SHA256
keys; Choose the one you need.
To get android key hash code follow these steps (for facebook apps)
- Download the openssl for windows here
- now unzip to c drive
- open cmd prompt
- type
cd C:\Program Files\Java\jdk1.6.0_26\bin
- then type only
keytool -export -alias myAlias -keystore C:\Users\<your user name>\.android\myKeyStore | C:\openssl-0.9.8k_WIN32\bin\openssl sha1 -binary | C:\openssl-0.9.8k_WIN32\bin\openssl enc -a -e
- Done
To get Certificate fingerprint(MD5) code follow these steps
- go to - C:\Program Files\Java\jdk1.6.0_26\bin
- inside the bin folder run the
jarsigner.exe
file - open cmd prompt
- type
cd C:\Program Files\Java\jdk1.6.0_26\bin
- then again type on cmd
keytool -list -keystore "C:/Documents and Settings/<your user name>/.android/debug.keystore"
- it will ask for Keystore password now. The default is "
android
" type and enter - Done.
keytool is part of the JDK.
Try to prepend %{JAVA_HOME}\
to the exec statement or c:\{path to jdk}\bin
.
I found this on another post, which did not get many upvotes, but it was super helpful for me. So will add it here.
Android Studio will bring a keytool with it.
C:\Program Files\Android\Android Studio\jre\bin
You can see his post below by Richar Heap, with a helpful reference. I did see this before but forgot about it. https://stackoverflow.com/a/51524526/4446406
The KeyTool is part of the JDK. You'll find it, assuming you installed the JDK with default settings, in $JAVA_HOME/bin
Robby Pond
's answer can be generalized to use JAVA_HOME
environment variable and to also compensate for any blanks that might occur in the path (like Program Files
):
"%JAVA_HOME%\bin\keytool" -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
keytool is part of jdk, it should be $JAVA_HOME/bin/keytool
keytool is located in JDK bin directory ($JAVA_HOME/bin). JAVA_HOME is your JDK installation directory. To use that command line you should also include $JAVA_HOME/bin to your PATH environment variable.
Keytool is part of the Java SDK. You should be able to find it in your Java SDK directory e.g. C:\Program Files\Java\jdk1.6.0_14\bin
On cmd window (need to run as Administrator),
cd %JAVA_HOME%
only works if you have set up your system environment variable JAVA_HOME . To set up your system variable for your path, you can do this
setx %JAVA_HOME% C:\Java\jdk1.8.0_121\
Then, you can type
cd c:\Java\jdk1.8.0_121\bin
or
cd %JAVA_HOME%\bin
Then, execute any commands provided by JAVA jdk's, such as
keytool -genkey -v -keystore myapp.keystore -alias myapp
You just have to answer the questions (equivalent to typing the values on cmd line) after hitting enter! The key would be generated
Android: where to run keytool command in android
Keytool command can be run at your dos command prompt, if JRE has been set in your classpath variable.
For example, if you want to get the MD5 Fingerprint of the SDK Debug Certificate for android,
just run the following command...
C:\Documents and Settings\user\.android> keytool -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android
where C:\Documents and Settings\user\.android>
is the path which contains the debug.keystore
that has to be certified.
For detailed information, please visit http://code.google.com/android/add-ons/google-apis/mapkey.html#getdebugfingerprint
Depending on your version of Eclipse ( I am using Kepler). Go to Windows> Preferences>Android> Build.
You'll find the location path of your debug keystore as well as the SHA1 fingerprint (which you can just copy and use)
If you installed visual studio with Xamarin/mobile development support, you'll have a java install here C:\Program Files\Android\jdk\microsoft_dist_openjdk_{version}\bin\
, as was my case.
KEYTOOL is in JAVAC SDK .So you must find it in inside the directory that contaijns javac
In addition to Gareth's
answer above, the below worked for me
Simply enter these into Windows command prompt.
Make sure the terminal is run as adminstrator
cd C:\Program Files\Android\Android Studio\jre\bin
keytool -list -v -keystore "C:\Users\admin.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

N:B: This should be done after the first build, as the keys are only generated after first build
keytool
comes with the JDK. If you are using cygwin then this is probably on your path already. Otherwise, you might dig around in your JDK's bin folder.
You'll probably need to use cygwin anyways for the shell pipes (|
) to work.
Few observations while I was getting the same problem (Windows). 1. Shell pipe is important. 2. If you are using OpenSSL or Cygwin, definitely you have to install it. 3. keytool comes with JDK so either you have to point to it in the command or you have cd to the JDK/bin folder (where the exe resides) 4. The debug keystore is typically located at ~/.android/debug.keystore 5. password is "android" whether you -keypass it or type it when prompted. 6. For the alias name, you can open (DO NOT SAVE, just open and close) the keystore file with any editor and read it. 7. MOST IMPORTANT - There is a difference is specifying the keystore path within quotes and without. I got it working by using the keystore path within the double quotes. As remix090378 said and as per the instruction, this command indeed worked - cd C:\Program Files\Java\jdk1.7.0_09\bin
keytool -exportcert -alias androiddebugkey -keystore "C:\Users\userName.android\debug.keystore" -list -v
Alternatively you can do the following :
- copy the bat file below in any folder already present in your
PATH
environment variable - then simply use
keytool
command in any Windows shell
Actual location of keytool is defined in the bat file. In case the location is wrong the bat file will scan your system to detect potential locations in ProgramFiles (sub)folders.
Also find keytool2.bat, a convinient shortcut for "keytool -v -list -keystore", which is widely used to quickly check the content of a jks file.
keytool.bat :

:: "keytool alias" script by Céphas
:: easy method : add the known keytool.exe folder to your personal PATH variable (run : C:\Windows\System32\rundll32.exe sysdm.cpl,EditEnvironmentVariables)
:: else, add the folder containing this bat script to your personal path or put this script in any folder already defined in your path
::
:: also see keytool2.bat that automatically adds the following parameters in the keytool command line : -v -list -keystore, for quick display of jks content

In my case, I had already generated an APK file using the command ionic cordova build android --prod
and I needed to get the SHA-1 fingerprint for the already existing APK file. Here's how I got it by running the following command in the App directory:
keytool -list -printcert -jarfile app-debug.apk
So, I basically ran the above command in the following app location:
C:\myApp\platforms\android\app\build\outputs\apk\debug>keytool -list -printcert -jarfile app-debug.apk
This gave me the SHA1 fingerprint as: 7B:6B:AD:...
Hope this helps someone!
On Windows
If your using Jetbrain's Toolbox, to manage Android Studio update, the path is something like
C:\Users\{USERNAME}\AppData\Local\JetBrains\Toolbox\apps\AndroidStudio\ch-0\202.7486908\jre\bin
After an update I have to manually update/set this path as JAVA_HOME
(the jre folder)
Consider adding PATH as an Environment variable and access it via cmd.
PATH as the value and C:\Program Files\Java\jre1.8.0_331\bin as the variable and access it via keytool ...
#Go to the path where cacerts or jsk is present and open and run below command on cmd
keytool -v -list -keystore cacerts
keytool -v -list -keystore .jks
Given that you have installed Java and preferably a JDK in your system ( answering for Windows because you mentioned it in your question) you should have the keytool utility on your installation's bin
folder.
If that's the case, what you can do next is add that bin folder to the PATH
environment variable of your Windows installation.
The next time you will open a Windows shell and you'll type keytool
you will be able to run the actual utility.
