Android : Invalid Key hash Android

I'm using facebook SDK for facebook login into my app. I have generated the key using the following command

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\ic
as2\.android\debug.keystore" | "C:\openssl\bin\openssl" sha1 -binary |"C:\openss
l\bin\openssl" base64

Generated key was

mW3....................CQc4=

Error i'm getting is

Invalid key hash. The key hash bMWwxx.................8BE does not match any stored
key hashes. Configure your app key hashes at http://developers.facebook.com/app/appID

Thanks in advance.
