CoreCrypt is a small tool designed to protect PHP and JavaScript scripts from being modified by unauthorized persons. It is addressed mainly to webmasters, who deal with professional website creation, giving them the opportunity to protect their product without affecting its functioning. The principle of the program is very simple and consists in a thorough analysis of the code and its modification so that it is as difficult to read and understand by unauthorized persons.

CoreCrypt removes all comments from the source code, folds it into a single line, making it unreadable, renaming variables and functions into more complicated and unrelated to their purpose, changing numerical values and character strings. The latter are encoded using Base64. All changes made by the tool do not affect in any way the operation of scripts, but only make it difficult to analyze and duplicate them.

The tool works well with protecting individual PHP and JS files, as well as their entire folders. A drag-and-drop method is supported for working with multiple scripts located in different locations.
