Answer 1

Try this:

MessageDigest mDigest=MessageDigest.getInstance("MD5");

mDigest.update("yourstring".getBytes());

byte d[]=mDigest.digest();
StringBuffer hash=new StringBuffer();

for (int i=0; i<d.length; i++) {
    hash.append(Integer.toHexString(0xFF & d[i]));
}
Log.d("Hash",hash.toString());

Answer 2

Look at the javax.crypto.Mac class. Try Mac.getInstance("HmacMD5"); and then use the init method with your key and then use the update and doFinal methods just as you would with a MessageDigest object.
