C:\Documents and Settings\Admin\ keytool -export -alias androiddebugkey -keystore "C:\Documents and Settings\Admin\.android\debug.keystore" | D:\openssl\bin\openssl.exe sha1 -binary | D:\openssl\bin\openssl.exe enc -a

I just run the above code for generating the hash key but it shows some errors...like

The filename ,directory name,or volume label syntax is incorrect

How to get Key Hashes for android-facebook app

If you still have the same problem then you may use the below code snippet to generate keyhash. This works perfectly fine for me.

PackageInfo packageInfo;
        try {
        packageInfo = getPackageManager().getPackageInfo("com.yourapp", 
PackageManager.GET_SIGNATURES);
        for (Signature signature : packageInfo.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                String key = new String(Base64.encode(md.digest(), 0));
                // String key = new String(Base64.encodeBytes(md.digest()));
                Log.e("Hash key", key);
        } 
        }
        catch (NameNotFoundException e1) {
            Log.e("Name not found", e1.toString());
        }

        catch (NoSuchAlgorithmException e) {
            Log.e("No such an algorithm", e.toString());
        }
        catch (Exception e){
            Log.e("Exception", e.toString());
        }

  • You may want to *explicitly* state that the code here came from the blog to which you link in the second line. It is **very good** that you provide a link to where you got the code. This code has been copied many times. You are only the second person I've seen that has bothered to state/imply the code came from somewhere else. – Makyen Feb 12 '17 at 07:32
