Facebook为Android生成Keyhash

Question

我遇到了在fb中生成keyhash的传统方法的问题， 这需要openssl和漫长的过程...

我想知道我是否可以输入28个随机字符并将该字符串用作我的keyhash？

           try {
              PackageInfo info = getPackageManager().getPackageInfo(
                "yourpackagename", 
                PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            Log.e("KeyHash:", Base64.encodeToString(md.digest(),Base64.DEFAULT));
            }
    } catch (NameNotFoundException e) {

    } catch (NoSuchAlgorithmException e) {

    }

//Call this method for KeyHash  
    String keyHash = getKeyHashForFacebook(SplashScreen.this);
    Log.e("keyHash  ", keyHash);


    public static String getKeyHashForFacebook(Context context) {
            try {
                PackageInfo info = context.getPackageManager().getPackageInfo(
                        context.getApplicationContext().getPackageName(), PackageManager.GET_SIGNATURES);
                for (Signature signature : info.signatures) {
                    MessageDigest md = MessageDigest.getInstance("SHA");
                    md.update(signature.toByteArray());
                    return "KeyHash:" + context.getApplicationContext().getPackageName() + "=>"
                            + Base64.encodeToString(md.digest(), Base64.DEFAULT);
                }
            } catch (Exception e) {
    e.printStackTrace();

            }
            return "=>";
        }
