title: Why keytool is generating different facebook androiddebugkey hash?
body: <p>I am creating Android application which use Facebook login SDK.</p>
  
  <p>I'd like to generate debug key hash. On Facebook website I found this command:</p>
  
  <blockquote>
    <p>keytool -exportcert -alias androiddebugkey -keystore
    %HOMEPATH%.android\debug.keystore | openssl sha1 -binary | openssl
    base64</p>
  </blockquote>
  
  <p>I modified this command to work on my computer:</p>
  
  <blockquote>
    <p>keytool -exportcert -alias androiddebugkey -keystore
    C:\Users\redio\.android\debug.keystore | "C:\OpenSSL\bin\openssl" sha1
    -binary |"C:\OpenSSL\bin\openssl" base64</p>
  </blockquote>
  
  <p>Next I entered password: android</p>
  
  <p>this command generated this hash: QUhvjKstiP5gc7hPEzwF89mwHws=</p>
  
  <p>then I pasted it in facebook developer console 
  and facebook is still saying that key hash is invalid. I know that I can copy the key hash from warning message, and paste it in facebook developer console. But my question is why keytool is generating wrong key hash?</p>
