Software protection tool. Its purpose is to selectively encrypt fragments of code in the program and add special code for stop debugging and disassembling. Features include: - polymorphic encryption with no constant signatures in encrypted fragments - encrypted fragment will only be decrypted immediately before its execution after the execution of the particular fragment it will be encrypted again (at any time during the execution there is only one protected fragment decrypted) - encryption has unlimited nesting (encrypted block inside encrypted block inside...) - single-use fragments: it is possible to mark a fragment of code so that fragment will be erased after the very first execution - user-key encryption - detect SoftIce, NtIce, FrogIce, TD and other debugger - detect registry/filesystem/API monitors - counteraction to dumping application with tools like ProcDump - anti-tracing measures - anti-disassembler measures - direct WinAPI support working around import table. - full integration with HardKey registration keymanager EXECryptor can protect any 32bit PE executable files. It was tested under W95/98/ME/2000/NT/XP. SDK available for Delphi, CBuilder, MSVC.
