Generating App Signature for Facebook Settings -1

Generating App Signature for Facebook Settings

To create facebook android native app you need to provide your Android application signature in facebook app settings. You can generate your application signature (keyhash) usingkeytool that comes with java. But to generate signature you need openssl installed on your pc. If you don’t have one download openssl from here and set it in your system environment path.

Open your command prompt (CMD) and run the following command to generate your keyhash. While generating hashkey it should ask you password. Give password as android. If it don’t ask for password your keystore path is incorrect.

keytool -exportcert -alias androiddebugkey -keystore "<path-to-users-directory>\.android\debug.keystore" | openssl sha1 -binary | openssl base64

check the following command how i generated hashkey on my pc.

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