Java - Encrypt part of the file(audio & image) instead of the whole file?
<p>I read something about this here
<a href="http://stackoverflow.com/questions/5003328/android-increase-speed-of-encryption">Android - Increase speed of encryption</a></p>

<p>I need to only encrypt part of the file(audio &amp; image). Is this possible? Can somebody provide snippet of both encryption and decryption if it's possible?</p>

<p>Thanks in advance =)</p>
