Android: How to Generate Key Hash for Facebook Integration

Hello everyone,

As this is a quite confusing for everyone to generate the key hash in your PC, so i decided to write about it. I have also tried many ways but every time i failed to generate the key hash.

After trying for an hour i successfully generated the key.

Just follow the below given Steps and you are done with this.

Step I: Download Openssl from here

Step II: Download openssl-0.9.8e_X64.zip for 64 bit PC and openssl-0.9.8e_WIN32.zip for 32 bit PC

Step III: once your download the zip folder. Go to C drive(where window is installed) and make a folder named openssl

Step IV: extract all zip file in this folder.

Step V: Now go to Java folder and copy path of jre. For example: C:\Program Files\Java\jre1.8.0_101\bin

(make sure your are in JRE folder not in JDK folder,)

Step VI: Now open Cmd in your PC. Type Cd C:\Program Files\Java\jre1.8.0_101\bin

Now copy the below code after this

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\John wick\.android\debug.keystore" | "C:\openssl\bin\openssl" sha1 -binary |"C:\openssl\bin\openssl" base64

instead of john wick you need to use your computer name. and the C:\openssl\bin\openssl is path where we extracted the zip file.

The whole command will be:

C:\Program Files\Java\jre1.8.0_101\bin> keytool -exportcert -alias androiddebugkey -keystore "C:\Users\John wick\.android\debug.keystore" | "C:\openssl\bin\openssl" sha1 -binary |"C:\openssl\bin\openssl" base64

After this cmd will promt you for password. Just enter “android”.

You will have your key hash in front of you.

Thanks, Happy Coding ;)
