Spring Boot Authorization Tutorial: Secure an API (Java)

Learn how to use Spring Boot, Java, and Auth0 to secure a feature-complete API. Learn how to use Auth0 to implement authorization in Spring Boot.

Learn how to secure an API with the world’s most popular Java framework and Auth0.

So far, you’ve built an API that allows anyone to read and write data. It’s time to tighten the security, so only users with the menu-admin role can create, update, and delete menu items.

Authentication vs. Authorization

To know what a user can do, you first need to know who the user is. This is known as authentication. It is often done by asking for a set of credentials, such as username & password. Once verified, the client gets information about the identity and access of the user.

To implement these Identity and Access Management (IAM) tasks easily, you can use OAuth 2.0, an authorization framework, and OpenID Connect (OIDC), a simple identity layer on top of it.

OAuth encapsulates access information in an access token. In turn, OpenID Connect encapsulates identity information in an ID token. The authentication server can send these two tokens to the client application initiating the process. When the user requests a protected API endpoint, it must send the access token along with the request.

You won’t have to worry about implementing OAuth, OpenID Connect, or an authentication server. Instead, you’ll use Auth0.

Auth0 is a flexible, drop-in solution to add authentication and authorization services to your applications. Your team and organization can avoid the cost, time, and risk that comes with building your own solution. Also, there are tons of docs and SDKs for you to get started and integrate Auth0 in your stack easily.

How to Validate an Email Address in Java

Email is one of the most universal tools for sharing and receiving information across the globe, with users able to connect with others online with almost no compatibility or access issues. Using this tool, information can be instantly and securely sent to partners on the other side of the world, and personal information can be verified without divulging sensitive data about a user.

Along with this widespread use, however, comes key security measures that must take place in order to ensure the safety of your organization and data. This is particularly the case when receiving email information from previously unknown sources. These risks can include phishing attempts, malware, and other threats that can cause a negative impact to your business. Furthermore, when receiving an email address via account forms and user sign up information, you need to check that the information you are given is not only correct and real, but also that it does not lead to any malicious sources that could harm your organizational security.

The following APIs will allow you to instantly verify and validate an input email address without sending any kind of notification to the email user. This will help protect your organization in the event of any threats. The goal of this tutorial is to provide you with the tools to protect your organization’s information while providing a way to verify new accounts and user information.

This will be done through three separate functions. The first will analyze the validity of an email address’ syntax. The second will check for the address’ servers, and the third performs a full email address validation including returning the results for the previous two functions.

How to Convert ODT Files to PDF in Java

Convert Office Open Document Text File (ODT) to standard PDF, DOCX, PNG, and JPG using Java.

Microsoft has maintained its position in the spotlight for formatted document creation and editing for good reason. Its extreme ease of use and lack of a learning curve has transformed the Microsoft Office Suite into a household name for most computer users in the United States as well as globally. This is propagated further through its almost ubiquitous use in education, as students are raised and taught using these applications.

The issue that arises with these programs, however, is their operation costs. For Apple and other non-Windows-based Operating Systems, the purchasing fees for Office can be steep. This, then, creates a paywall separating potential users from programs to which they are already accustomed. As an answer this problem, Microsoft created the OpenOffice application, which is a free, opensource version of the classic Office Suite. Within this application, you can perform almost all of the same functions as Office Suite, including creating text documents like one would with Microsoft Word. These text documents can be made using OpenOffice Writer, and are formatted using the .ODT file type. While this file type can be opened and saved using OpenOffice Writer and Word, in order to convert the file to a different format such as PDF you will need to run it through a conversion process.

The following APIs will allow you to convert your ODT documents to PDF, DOCX, PNG, and JPG for use in whatever way you need. The goal of this tutorial is to provide a simple and efficient means for instantly converting your ODT files without needing to find or download any extraneous programming.
