Android初学------MD5加密

/*** * MD5 * @param inputStr * @return * @throws NoSuchAlgorithmException */public static String md5(String inputStr) throws NoSuchAlgorithmException {    String md5Str = inputStr;    if(inputStr != null) {        MessageDigest md = MessageDigest.getInstance("MD5");        md.update(inputStr.getBytes());        BigInteger hash = new BigInteger(1, md.digest());        md5Str = hash.toString(16);        if((md5Str.length() % 2) != 0) {            md5Str = "0" + md5Str;        }    }    return md5Str;}

以后说不定用得着，留着。
