How can I find and run the keytool

Question

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)

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.

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
