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.

Accepted Answer

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

To get android key hash code follow these steps (for facebook apps)

  1. Download the openssl for windows here
  2. now unzip to c drive
  3. open cmd prompt
  4. type cd C:\Program Files\Java\jdk1.6.0_26\bin
  5. 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
  6. Done

To get Certificate fingerprint(MD5) code follow these steps

  1. go to - C:\Program Files\Java\jdk1.6.0_26\bin
  2. inside the bin folder run the jarsigner.exe file
  3. open cmd prompt
  4. type cd C:\Program Files\Java\jdk1.6.0_26\bin
  5. then again type on cmd keytool -list -keystore "C:/Documents and Settings/<your user name>/.android/debug.keystore"
  6. it will ask for Keystore password now. The default is "android" type and enter
  7. Done.

keytool is part of the JDK.

Try to prepend %{JAVA_HOME}\ to the exec statement or c:\{path to jdk}\bin.

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
