title: I'm setting up facebook Account Kit SMS Authentication, Is it necessary to generate hash key?
body: <p>Can I just get app id and facebook account kit from facebook developers ?
  I launch The Command Prompt and go to my java bin directory and execute the following command : keytool -exportcert -alias androiddebugkey -keystore C:\Users\Ousama.android\debug.keystore |
  "C:\Users\Ousama\Desktop\openssl-0.9.8k_X64\bin\openssl.exe" shal -binary | "C:\Users\Ousama\Desktop\openssl-0.9.8k_X64\bin\openssl.exe" base64.
  But i don't have any output, he just say that the syntaxe of the command (keytool -exportcert -alias androiddebugkey -keystore ) is incorrect !</p>
