Rapid DeCoder

Rapid DeCoder is an open-source unescape() JavaScript decoder, capable of processing values which have been encoded in hexadecimal format. It mainly caters to professional users, such as JavaScript developers.
This lightweight application is portable, meaning that you can drop the executable file anywhere on the hard disk and click it to run.
As an alternative, Rapid DeCoder can be saved to a USB flash disk or similar storage unit, from where you can run it on any computer with minimum effort.
What's more, the app does not add new entries to the Windows registry, Start menu, or any other part of the disk. A simple file deletion is suffice to accomplish this task.
The interface is made from a single window divided into two areas dedicated to the encrypted and decrypted format, respectively. All you have to do is write the encrypted text and click a button to view results on the fly.
Although Rapid DeCoder does not provide buttons for copying text to the Clipboard or exporting it to file, it is possible to make a selection and copy it via the right-click menu.
The application has a minimal impact on system resources, using a low amount of CPU and RAM. No error dialogs have been shown in our tests, and the tool did not hang or crash. When it comes down to it, Rapid DeCoder serves its purpose without any issue.
