How can I find and run the keytool

Question

I am reading an development guide of Facebook Developers at here

It says that I must use keytool to export the signature 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.

Answer 1

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.

6. Done

To get Certificate fingerprint(MD5) code follow these steps

1. go to - C:\Program Files\Java\jdk1.6.0_26\bin

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.

Answer 4

KEYTOOL is in JAVAC SDK .So you must find it in inside the directory that contaijns javac

Answer 5

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.

Answer 6

keytool is part of jdk, it should be $JAVA_HOME/bin/keytool
