AS7: Utilising masked passwords via the vault

Background:

JBoss AS7.1 includes a vault facility to secure attributes (such as passwords). 

You can get more information at https://community.jboss.org/wiki/JBossAS7SecuringPasswords

 

Example:

Assume that I want to obtain a datasource in my servlet.  This is a very simple example.

 

The servlet would look like the following:

 

package vaulterror.web;

import java.io.IOException;
import java.io.Writer;

import javax.annotation.Resource;
import javax.annotation.sql.DataSourceDefinition;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.sql.DataSource;


/*@DataSourceDefinition(
        name = "java:jboss/datasources/LoginDS",
        user = "sa",
        password = "sa",
        className = "org.h2.jdbcx.JdbcDataSource",
        url = "jdbc:h2:tcp://localhost/mem:test"
)*/
@DataSourceDefinition(
        name = "java:jboss/datasources/LoginDS",
        user = "sa",
        password = "VAULT::DS::thePass::OWY5M2I5NzctYzdkOS00MmZhLWExZGYtNjczM2U5ZGUyOWIxTElORV9CUkVBS3ZhdWx0",
        className = "org.h2.jdbcx.JdbcDataSource",
        url = "jdbc:h2:tcp://localhost/mem:test"
)
@WebServlet(name = "MyTestServlet", urlPatterns = { "/my/" }, loadOnStartup = 1)
public class MyTestServlet  extends HttpServlet {

    private static final long serialVersionUID = 1L;


    @Resource(lookup = "java:jboss/datasources/LoginDS")
    private DataSource ds;

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        Writer writer = resp.getWriter();
        writer.write((ds != null) + "");
    }
}

 

Note that I have commented out one @DataSourceDefinition annotation.  That includes the clear text database password.  In this example, we use the H2 database that is available for use in JBoss AS7.1

 

The uncommented @DataSourceDefinition  contains the masked password via the vault.

I entered "sa" for the attribute value.

I entered "vault22" for keystore password

 

 

My standalone/configuration/standalone.xml contains the following

 

<?xml version='1.0' encoding='UTF-8'?>

<server name="localhost.sadbhav" xmlns="urn:jboss:domain:1.1" xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance">

    <extensions>
       ...

    <vault>
      <vault-option name="KEYSTORE_URL" value="${user.home}/vault/vault.keystore"/>
      <vault-option name="KEYSTORE_PASSWORD" value="MASK-3y28rCZlcKR"/>

      <vault-option name="ITERATION_COUNT" value="50"/>
      <vault-option name="ENC_FILE_DIR" value="${user.home}/vault/"/>
    </vault>
    <management> ....

 

When I go to the web application, http://localhost:8080/vaulterror-web-1.0-SNAPSHOT/my/

I get the value "true".
