Defence Suite - package of components for managing licenses for developers Borlan Delphi, wanting to ensure the protection of their programs from non-authorized use.
Encrypting License
Generation license-file occurs on the side of the developer, ie no generators serial numbers in the program. File-license is encrypted (for transmission) algorithm RC4, based on data received from the user. Encryption is provided by Microsoft CryptoAPI 2.0 at work running Windows 2000, 2003 Server, XP (for Windows 98 - must install Internet Explorer 5, also need to ask for Delphi-project setting conditional compilation NT5, then the function calls that have emerged only in Windows 2000 will work normally)
Multi-level verification
In preparing the license you can configure rules check: username, email address, ID, HDD-serial or MAC-address, date of license expiration, date of generation licenses, checksum program, the correctness of key generation.
Storage area
These licenses can be saved as a file, or in the form of data in the registry key operating systems, or on server in network.
Detection virtual OS
Supports detection run your program running virtual OS: VMware, VPC
