SDProtector Basic Description:

SDProtector is a powerful tool offering both software developers and distributors a protection of software products against unauthorized copying, use and distribution. SDProtector was designed with ease of use and high speed as a priority without sacrificing high levels of protection. It offers four different methods of code encryption protection. In addition, it uses RSA 1024 algorithm, API functions, new anti-debug tricks, active protection against dumping from memory and tracers. With SDProtector it's easy to turn your application in "try-before-you-buy" versions with little effort, offering everything to guarantee a maximum protection against piracy, backdating, reverse-engineering or any kind of tampering

Key Features:

compression of the application - up to 60%
encryption of the application
counteraction to dumping application memory with ProcDump-like tools.
application integrity check
powerful protection against most known (and unknown) debuggers
ability to perform runtime protection, protect your program not only during start but always while its running

counteracts disassemblers- defeat reverse engineering!
counteraction to memory patching
defeat API hook (protect any special technique you use)
API for interaction between application and protection routines
runtime code en-/decryption
encryption of license-specific code
ability to add embedded protector to your code
automation of license generation
licensing system featuring up to 1024 bit public key cryptography
registration via keyfiles or text keys
blacklisting of stolen or compromised keys
detects backdating or reinstallation to gain additional usage
ability to create trial keys and hardware dependent keys
Invisible software based protection requiring no dongles
Compatible with Windows 98, Me, NT, 2000, XP, 2003 server
