Facebook Android Generate Key Hash

Scott picture Scott · Mar 15, 2011 · Viewed 213.8k times · Source

Trying to create an android app with Facebook integration, I've gotten to the part in the docs where you have to generate a key hash file, it specifies to run the following code

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore 
| openssl sha1 -binary
| openssl base64

When I run this in my terminal I get an error for Keystore tampered with or password was incorrect,

I just want to generate my Key Hash

Can anyone point me in the right direction?

In order to generate key hash you need to follow some easy steps.

1) Download Openssl from: here.

2) Make a openssl folder in C drive

3) Extract Zip files into this openssl folder created in C Drive.

4) Copy the File debug.keystore from .android folder in my case (C:\Users\SYSTEM.android) and paste into JDK bin Folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin)

5) Open command prompt and give the path of JDK Bin folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin).

6) Copy the following code and hit enter

keytool -exportcert -alias androiddebugkey -keystore debug.keystore > c:\openssl\bin\debug.txt

7) Now you need to enter password, Password = android.

8) If you see in openssl Bin folder, you will get a file with the name of debug.txt

9) Now either you can restart command prompt or work with existing command prompt

10) get back to C drive and give the path of openssl Bin folder

11) copy the following code and paste

openssl sha1 -binary debug.txt > debug_sha.txt

12) you will get debug_sha.txt in openssl bin folder

13) Again copy following code and paste

openssl base64 -in debug_sha.txt > debug_base64.txt

14) you will get debug_base64.txt in openssl bin folder

15) open debug_base64.txt file Here is your Key hash.
