How to create Facebook Hash Key in android ?

This is simple process to generate Hash key and we already create lots of time but again we forget that how to generate Hash key ? Even i am stupid one

of them and again throw same query in Google. But Now i remember whole the process to generate hash key. When you start to create new

Facebook application for android they ask Hash Key to validate your application.

Most of the time user confused to generate Hask key and Key Store , They confused that from where to start ? It mean which path should be use to generate

key?

How to Generate android (Facebook ) Hash Key ?

Step 1 :  Download OpenSSL for Windows 

Step 2 : Open the drive where you have install JDK. ,(in my case that is C:\)

Step 3 : Extract your Open SSL zip here in root directory (in my case C:\Program Files\)Step 4 :  Copy :  JAVA > JDK 1.7.0_25 > bin 

Step 5 :  Open Command prompt , Start > Run > CMD 

Step 6 : Now CMD will show User’s location (in my case C:\Users\chintan >_ )Step 7 : Using Step 4 paste that copied path here and enter ,So it looks like this C:\Users\chintan > cd C:\Program Files\Java\jdk1.7.0_25\bin

Enter , so that will switch to new location. So now you should be here C:\Program Files\Java\jdk1.7.0_25\bin >_  Step 8 :  Now start from here ,

 8.1 keytool -export -ali as myAl ias  (set alias name any) 

 8.2 C:\Users\chintan\.android\debug.keystore  ,(Get your Debug key store path and append after alias ) 

 8.3 C:\openssl-0.9.8k_WIN32\bin\openssl sha1 -binary(Get your openssl path and append after keystore pathseparate with "|") 8.3 C:\openssl-0.9.8k_WI N32\bin\openssl enc -a -e  (append with "|") 

So , whole URL should looks like ,

Step 9 : Enter if you are ready to get Hash Key :)C:\Program Files\Java\jdk1.7.0_25\bin >keytool -export -alias myAlias -keystore C:\Users\chintan\.android\debug.keystore | C:\openssl-0.9.8k_WIN32\bin\openssl sha1 -binary| C:\openssl-0.9.8k_WIN32\bin\openssl enc -a -e 

Check three parts in your environment.

1. where is "debug.keystore"?

find / -name "debug.keystore" if you can't find it, check you eclipse or ADT.

2. what is alias name?

keytool -list -v -keystore "PATH_TO_DEBUG_KEYSTORE" 

3. Check if installed openssl 

openssl 

If everything is ready, it should prompt for password

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.

OLD ANSWER (Generating Keyhash using openssl )

1. to generate signature you need openssl installed on your pc. If you don’t have one download opensslfrom here 

2. In C: , Create openssl folder

3. extract the contents of downloaded openssl zip file into openssl folder in C:drive

4. open Command prompt

5. move to bin of openssl i.e C:\openssl\bin  in command prompt

6. run the following command to generate your keyhash. While generating hashkey it should ask you password.

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\Anhsirk.android\debug.keystore" | openssl sha1 -binary |

openssl base64

NOTE: in the above code note that , you need to give your path to user  ( i.e in my case it is C:\Users\Anhsirk , you just need to

change this for your user account.Give password as android 

. If it don’t ask for password your keystore path is incorrect.

If everything works fine, it should give you the hashkey below.

II. Create key hash release for facebook 

1. Download Openssl from: http://code.google.com/p/openssl-for-windows/downloads/list download openssl-0.9.8e_X64

2. Make a openssl folder in C drive

3. Extract Zip files into openssl folder

4. Start -> Run: cmd (press enter)

5. (press) cd C:\Program Files\Java\jdk1.6.0_45\bin. Note: C:\Program Files\Java\jdk1.6.0_45\bin: is path to jdk folder in your

computer

6. (press) keytool -exportcert -alias gci -keystore D:\folder\keystorerelease | C:\openssl\bin\openssl sha1 -binary |

C:\openssl\bin\openssl base64. Note: D:\folder\keystorerelease: is path to your keystorerelease

7. Enter keystore password: This is password when your register keystorerelease.

Then you will have a key hash: jDehABCDIQEDWAYz5Ow4sjsxLSw=

8. Login facebook. Access to Manage Apps. Paste key hash to your app on developers.facebook.com
