• 8.2 C:Userschintan.androiddebug.keystore,(Get your Debug key store path and append after alias )

• 8.3 C:openssl-0.9.8k_WIN32binopenssl sha1 -binary(Get your openssl path and append after keystore path separate with '|') 8.3 C:openssl-0.9.8k_WIN32binopenssl enc -a -e (append with '|')

So , whole URL should looks like ,

Step 9 : Enter if you are ready to get Hash Key 🙂
