eXPressor is a tool for software protection and file compression, designed specifically for .exe files. It combines these two functions into a single application that can help improve security and reduce file size.

In addition to compression, eXPressor also offers robust protection against crackers. It can help developers create uncrackable registration keys and implement trial versions for their software. Other features include customizable resource compression, password protection, counteraction to classical memory dumping tools, and detection of cracking tools like file or registry monitors and debuggers.
eXPressor also employs anti-debugging and anti-disassembling techniques and anti-memory patching techniques that protect imported functions. The software offers a set of APIs for interaction between decompressing routines and protected applications. It features a registration keys system that uses RSA-based encryption/decryption algorithm, and keys can be generated using specific hardware ID, eliminating the possibility of key generators.
The software also supports the management of stolen registration keys and the creation of trial versions with limited functionality and evaluation time. Additionally, it offers shell integration, project file saving, command-line support, and more. The eXPressor software is an essential tool for developers who want to protect their software from crackers and compress their files without sacrificing performance.
