Php Code Encoding Benefits or which Encoder do I Need?

Php Code Encoding Benefits or which Encoder do I Need?

Encoding Benefits

PHP scripts can be easily read, changed and run on any PHP enabled system. Encoding PHP offers important benefits.

Product Developers: protect and license your code before distribution. Time restricting is ideal for protecting evaluation copies, and server/domain based locking helps secure revenue from multiple domain deployments.

Website Designers: protect your creative work and a revenue stream from future script updates.

Enterprise Customers: successfully enforce internal change control policies by avoiding untracked software tweaks that may get lost on a site reinstall or server move.

Website Owners: hide sensitive data and protect scripts from unauthorised changes that may go unnoticed indefinitely, and be a serious security and data protection risk.

Which Encoder do I Need?

The following guide will help you choose the right Encoder edition for your needs.

Product Developers: Pro or Cerberus
Pro and Cerberus provide PHP encoding plus the ability to create license files for your products. License files can protect your scripts against unauthorised use by locking to specific machines. They can also time expire, which is ideal for releasing evaluation versions. The Windows Pro or Cerberus Encoder also comes with a license generator for Linux, which may be useful for automating license generation from a web server.

Website Designers: Pro, consider Cerberus
As a designer, you may wish to provide early versions of your work to the client before completion. You want the code to run, but not forever. Pro and Cerberus allow you protect your files to expire at some point in the future, allowing clients to try protected code for a limited time.

Enterprise Customers: Basic, consider Pro or Cerberus
The main requirement is likely to be code protection, and the basic version is sufficient for this task. If you would also like to lock files to their intended server, then Pro and Cerberus allow this.

Website Owners: Basic, consider Pro or Cerberus
Your website files are likely to be specific just to your needs, and so the main requirement is encoding. The Basic version offers this, while Pro or Cerberus would reduce the risk of any stolen files being run on another server.

How to protect and hide PHP source code?

How to protect and hide PHP source code?

In the time of open-source there are multiple benefits of making your code available to all. However when deploying or selling your PHP code to a client you might want to protect and hide it because of different business reasons or security.

There are multiple approaches to check based on the use cases:

  • Obfuscation – makes code difficult to read by a human in order to hide its logic or purpose. In most cases the reverse-engineering of such code is still possible so obfuscation doesn’t provide proper code protection if you need it.
  • SaaS – Software as a service is code licensing approach where the code is accessed from a server based on licenses and subscriptions to enabled users. Consider this kind of way if you want to make sure that the code is not available to end-users or that it is used only on request.
  • License agreements and contracts are the usual approach to make agreements between coders with clients.
