Remove the cd in your command. You don't want to change to the directory, just give the full path to keytool.exe — brianestey, Nov 09 '11 at 08:38
@brianestey: If i remove the cd then it will say that "C:\Program" is not recognized as an internal or external command. — Shreyash Mahajan, Nov 09 '11 at 08:50
That's why you need quotation marks around the full path "C:\Program Files\..." — brianestey, Nov 09 '11 at 08:53

I have keytool in a different directory:

C:\Program Files (x86)\Java\jre6\bin

You can either add the path where keytool is into your PATH environment variable, or you can use quotes around the full path like

D:\Users\Priyadarshan.android>"C:\Program Files\etc\keytool.exe" -exportcert etc etc

Don't forget the quotation marks because of spaces in the path!

keytool comes with the JDK.

You'll find it, assuming you installed the JDK with default settings, at C:\Program Files\Java\jdk1.6.0_23\bin\keytool.exe

THE Coder from facebook documentation to get the hash code just run it in the emulator

   try {
            PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md;

                    md = MessageDigest.getInstance("SHA");
                    md.update(signature.toByteArray());
                    String something = new String(Base64.encode(md.digest(), 0));
                   //Toast.makeText(StartingPlace.this, something,
                        //  Toast.LENGTH_LONG).show();
                    Log.e("hash key", something);
        } 
        }
        catch (NameNotFoundException e1) {
            // TODO Auto-generated catch block
            Log.e("name not found", e1.toString());
        }

             catch (NoSuchAlgorithmException e1) {
                // TODO Auto-generated catch block
                 Log.e("no such an algorithm", e1.toString());
            }
             catch (Exception e1){
                 Log.e("exception", e1.toString());
             }
        //code to get hash code
