Subject: MD5 example
Dear Hardeep,
I have included an example of MD5 for you.
If you want to use the 16 byte data instead of convert it to hex string
just return the md5.digest().
Hope this helps.

/**
Generate a MD5 digest and return as hex.
@param s String for which MD5 is to be generated.
@returns 32 character hex representation of the MD5
digest.
*/
public static String md5Hex(String s)
throws NoSuchAlgorithmException{
MessageDigest md5 = MessageDigest.getInstance("MD5");
md5.update(s.getBytes());
return bytesToHexString(md5.digest());
}
public static String bytesToHexString(byte[] b){
char[] hexChars = {'0','1','2','3','4','5','6','7',
'8','9','A','B','C','D','E','F'};
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < b.length; i++){
hexString.append(hexChars[(b[i] >> 4) & 0x0f]);
hexString.append(hexChars[b[i] & 0x0f]);
}
return hexString.toString();
}
