eXPressor - Software Protection System and PE Compressor. Used as a compressor this tool can compress EXE files to half their normal size. Once compressed, the files execute just like normal.

As a protector It is designed to protect applications against crackers.

Also can help developers in creation of uncrackable registration keys, and implementation of trial version for protected software.

Features:
-excelent compression ratios ~70% (this is
-tighter than .rar, .zip, upx etc.);
-multilevel packing (over and over the same file);
-support for various 32bit PE files like .exe, .dll, .net, .ocx, .scr;
-customizable resource compression;
-password protection for applications;
-counteraction to classical memory dumping tools;
-detection of cracking tools like file or registry monitors, debuggers;
-application integrity check (agains viruses, resource modifications);
-anti
-debugging and anti
-disassembling;
-anti memory patching techniques;
-protection of application's imported functions using different methods (emulation etc.);
-eXPressor offers a set of APIs for interaction betweend decompressing routines and protected applications;
-registration keys system using RSA based encryption/decryption algorithm;
-keys can be generated using specific hardware ID; say STOP to your application keygenerators; "
-stolen" registration keys management, integration of stolen keys in new protected versions of the application;
-eXPressor offers the possibility of creating "trial" versions of the application, with limited functionality, and limited evaluation time or number of executions;
-reminder message in unregistered version of protected programs;
-shell integration, project file saving, command line support and more
