Java字符串到SHA1

这是我将字符串转换为sha1的解决方案。它在我的Android应用程序中运行良好：

private static String encryptPassword(String password){    String sha1 = "";    try    {        MessageDigest crypt = MessageDigest.getInstance("SHA-1");        crypt.reset();        crypt.update(password.getBytes("UTF-8"));        sha1 = byteToHex(crypt.digest());    }    catch(NoSuchAlgorithmException e)    {        e.printStackTrace();    }    catch(UnsupportedEncodingException e)    {        e.printStackTrace();    }    return sha1;}private static String byteToHex(final byte[] hash){    Formatter formatter = new Formatter();    for (byte b : hash)    {        formatter.format("%02x", b);    }    String result = formatter.toString();    formatter.close();    return result;}
