Using XML Digital Signatures for Application Licensing. Introduction At some point in most developers' lives, application licensing becomes a problem.
Many solutions exist but are often expensive and difficult to implement. Few offer seamless integration with an existing code base. In such a case, writing an in-house licensing mechanism may be desired. Such a task, however, is faced with many problems. One of the biggest challenges of any licensing mechanism is to create a scheme that can't be hacked by the user. Such a solution does exist: XML Digital Signatures. This article will explain the basic premise public-key cryptography and how it relates to XML Digital Signatures, detail the creation of a key pair, give examples for signing and verifying an XML document, and discuss different implementations to provide reliable application licensing.
Note: this is not a full solution that you can simply add to your application, but a tutorial about how to sign XML using XML Digital Signatures.
Licensing management. Spring Security Tutorial: REST with Basic Authentication. Configuring Spring Security for a RESTful Web Services – NetworkedAssets. Recently, I have spent some time searching for the solution of the following problem: how to secure a RESTful service with a Spring Security framework without using the login form?
I haven’t found a satisfactory answer for my question. After a couple of hours I have implemented the solution successfully, I searched through all the tips and suggestions in tutorials and forums. I hope that this solution will be helpful to someone and will save much valuable time. So let’s get to work… Problem description. Security. 12. Session Management. HTTP session related functonality is handled by a combination of the SessionManagementFilter and the SessionAuthenticationStrategy interface, which the filter delegates to.
Typical usage includes session-fixation protection attack prevention, detection of session timeouts and restrictions on how many sessions an authenticated user may have open concurrently. 12.1 SessionManagementFilter The SessionManagementFilter checks the contents of the SecurityContextRepository against the current contents of the SecurityContextHolder to determine whether a user has been authenticated during the current request, typically by a non-interactive authentication mechanism, such as pre-authentication or remember-me .
If the repository contains a security context, the filter does nothing. If it doesn't, and the thread-local SecurityContext contains a (non-anonymous) Authentication object, the filter assumes they have been authenticated by a previous filter in the stack. 12.2 SessionAuthenticationStrategy. Web development - License key solution in web application, what is the best approach? Software License Management and Software Activation. Per-seat license. A Per-seat license is a software license based on the number of individual users who have access to the software.
For example, 50-user per-seat license would mean that up to 50 individually named users can access the program (compare named user licensing). Per seat licensing is administered by providing user-level security to the directory containing the program. The alternative is a concurrent user license, based on the number of simultaneous users—regardless of which individuals they are—accessing the program. It typically deals with software running in the server where users connect via the network.
What is the difference between core-based and u... Why Enterprise Clients Should Choose User-based Software Licensing Metrics. I am a technology attorney in Texas specializing in software license transactions and disputes with the major software publishers including Microsoft, Adobe, Oracle and IBM.
I represent some of the world’s largest corporations in enterprise software license transactions. I have been involved in more than 600 software license disputes in the last 10 years and during that time I have discovered that device- based licensing leads to many compliance problems that could be easily avoided. I have been encouraging my clients to move toward user-based metrics for many years, and the market trends are moving in that direction.
International Free and Open Source Software Law Review. Open source licensing notices in Web applications Arnoud Engelfriet a DOI: 10.5033/ifosslr.v3i1.47 Abstract More and more applications are moving to the Web.
Often, such applications present a combination of client- and server-side code. Keywords. Five affordable apps for managing software licenses. If you're a busy IT admin, one of the last things you need to deal with is a missing software license.
The simple loss of a string of characters can lead you into a tailspin of frustration — dealing with vendors to reclaim those licenses or worse, having to re-purchase the same software. Instead of risking such a loss, why not employ an app to help you keep track of those licenses? Plenty of solutions are available to you. Some are geared specifically for that purpose; others are equally capable, though intended for a different purpose use. Let's examine five apps that will help you keep those licenses safe from absentmindedness or disaster.
