Changes to the SecretKeyFactory API in Android 4 4

Posted by Trevor Johns, Android Developer Relations team

In order to encrypt data, you need two things: some data to encrypt and an encryption key. The encryption key is typically a 128- or 256-bit integer. However, most people would rather use a short passphrase instead of a remembering a 78-digit number, so Android provides a way to generate an encryption key from ASCII text inside of javax.crypto.SecretKeyFactory.

Beginning with Android 4.4 KitKat, we’ve made a subtle change to the behavior of SecretKeyFactory. This change may break some applications that use symmetric encryption and meet all of the following conditions:

1. Use SecretKeyFactory to generate symmetric keys, and


2. Use PBKDF2WithHmacSHA1 as their key generation algorithm for SecretKeyFactory, and


3. Allow Unicode input for passphrases

Specifically, PBKDF2WithHmacSHA1 only looks at the lower 8 bits of Java characters in passphrases on devices running Android 4.3 or below. Beginning with Android 4.4, we have changed this implementation to use all available bits in Unicode characters, in compliance with recommendations in PCKS #5.

Users using only ASCII characters in passphrases will see no difference. However, passphrases using higher-order Unicode characters will result in a different key being generated on devices running Android 4.4 and later.

For backward compatibility, we have added a new key generation algorithm which preserves the old behavior: PBKDF2WithHmacSHA1And8bit. Applications that need to preserve compatibility with older platform versions (pre API 19) and meet the conditions above can make use of this code:

import android.os.Build;
 
SecretKeyFactory factory;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
   // Use compatibility key factory -- only uses lower 8-bits of passphrase chars
   factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1And8bit");
} else {
   // Traditional key factory. Will use lower 8-bits of passphrase chars on
   // older Android versions (API level 18 and lower) and all available bits
   // on KitKat and newer (API level 19 and higher).
   factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
}

Android Gallery Control

In Android the Gallery control is a selection control that displays items in a horizontal gallery. the items in the gallery appear beside each other. they can appear separated by a pre-defined space.

remember that there is a sample demo application for the gallery to download at the end of the post

we can use the gallery to display String items using a simple ArrayAdapter.
so lets see how to create a gallery that displays the word "Hello" in several languages:

the layout:

01	<?xml version="1.0" encoding="utf-8"?>

02	<LinearLayout >="http://schemas.android.com/apk/res/android"

03	android:orientation="vertical"

04	android:layout_width="fill_parent"

05	android:layout_height="fill_parent"

06

>

07

<TextView

08	android:layout_width="fill_parent"

09	android:layout_height="wrap_content"

10	android:text="Gallery Demo"

11

/>

12

<Gallery

13	android:id="@+id/gallery"

14	android:layout_width="fill_parent"

15	android:layout_height="wrap_content"

16	android:gravity="center_horizontal"

17	android:spacing="100px"

18

19

/>

20	</LinearLayout>

and in the OnCreate method

01

@Override

02	public void onCreate(Bundle savedInstanceState) {

03	super.onCreate(savedInstanceState);

04	setContentView(R.layout.main);

05	gallery=(Gallery)findViewById(R.id.gallery);

06	//String array holding the values

07	String [] text=new String[]{"Hello","Hi","Alloha","Bonjour","Hallo","¡Hola"};

08	//Array adapter to display our values in the gallery control

09	ArrayAdapter<string> arr=new ArrayAdapter<string>(this, android.R.layout.simple_gallery_item, text);

10	gallery.setAdapter(arr);

11

}

12	</string></string>

the gallery will be like this

we can increse the spacing between the items by increasing the value of android:spacing property.

we can display a scroll bar to indicate the position of the current selected item in the gallery like this:

01

<Gallery

02	android:id="@+id/gallery"

03	android:layout_width="fill_parent"

04	android:layout_height="wrap_content"

05	android:gravity="center_horizontal"

06	android:spacing="100px"

07	android:scrollbars="horizontal"

08	android:scrollbarFadeDuration="0"

09	android:scrollX="100px"

10

/>

setting the android:scrollbarFadeDuration="0" makes the scroll bar always visible.

The android:scrollX property defines the initial scroll offset of the scroll bar which is the initial distance that the gallery is scrolled for.

Handling Gallery Events
since the gallery is a selction Control (a adapter view) so it can register a OnItemSelectedListener to handle the selection of items within the gallery.

01	final String [] text=new String[]{"Hello","Hi","Alloha","Bonjour","Hallo","¡Hola"};

02	gallery.setOnItemSelectedListener(new OnItemSelectedListener() {

03

04

@Override

05	public void onItemSelected(AdapterView parent, View view,

06	int position, long id) {

07	// TODO Auto-generated method stub

08	TextView txt=(TextView)findViewById(R.id.txt);

09	txt.setText(text[position].toString());

10

}

11

12

@Override

13	public void onNothingSelected(AdapterView parent) {

14	// TODO Auto-generated method stub

15

16

}

17

});

now the final step is to add two navigation buttons: Next and Previous to navigate throught the items in the gallery.
the layout is gonna be like this:

01	<?xml version="1.0" encoding="utf-8"?>

02	<LinearLayout >="http://schemas.android.com/apk/res/android"

03	android:orientation="vertical"

04	android:layout_width="fill_parent"

05	android:layout_height="fill_parent"

06

>

07

<TextView

08	android:layout_width="fill_parent"

09	android:layout_height="wrap_content"

10	android:text="Gallery Demo"

11	android:id="@+id/txt"

12

/>

13

<Gallery

14	android:id="@+id/gallery"

15	android:layout_width="fill_parent"

16	android:layout_height="wrap_content"

17	android:gravity="center_horizontal"

18	android:spacing="100px"

19	android:scrollbars="horizontal"

20	android:scrollbarFadeDuration="0"

21	android:scrollX="100px"

22

/>

23	<LinearLayout

24	android:layout_width="fill_parent"

25	android:layout_height="wrap_content"

26	android:orientation="horizontal"

27	android:layout_marginTop="5px"

28

>

29

<Button

30	android:text="Previous"

31	android:layout_width="wrap_content"

32	android:layout_height="wrap_content"

33	android:id="@+id/btnPrev"

34	android:onClick="onClick"

35

/>

36

<Button

37	android:text="Next"

38	android:layout_width="wrap_content"

39	android:layout_height="wrap_content"

40	android:id="@+id/btnNext"

41	android:onClick="onClick"

42

/>

43

44	</LinearLayout>

45

46	</LinearLayout>

now in order to keep track of the index of the currently selected item we need to define two variables

1	//Variable to store the number of items in the gallery

2	int ItemsInGallery=0;

3	int CurrentIndex=0;

and the navigation buttons click handlers:

01

@Override

02	public void onClick(View v) {

03	// TODO Auto-generated method stub

04	switch(v.getId())

05

{

06	case R.id.btnNext:

07	//Increase the index

08	CurrentIndex++;

09	//if reached the end of the gallery, then start from the first item

10	if(CurrentIndex>ItemsInGallery-1)

11	CurrentIndex=0;

12	gallery.setSelection(CurrentIndex,true);

13	txt.setText(String.valueOf(CurrentIndex));

14

break;

15	case R.id.btnPrev:

16	//Decrease the index

17	CurrentIndex=CurrentIndex-1;

18	//If reached the first item, then return to the last item in the gallery

19	if(CurrentIndex<0)

20	CurrentIndex=ItemsInGallery-1;

21	gallery.setSelection(CurrentIndex,true);

22	txt.setText(String.valueOf(CurrentIndex));

23

break;

24

}

25

}
