Description
PSIKEY 2.DLL is a dynamic link library (DLL) file that is utilized by software applications for licensing and digital rights management (DRM) purposes. It is typically associated with the software protection system called “PSI” (Protection Software InstallShield) developed by Macrovision. This DLL plays a vital role in verifying the legality of the software installation and ensuring that the appropriate licensing requirements are met.
The PSIKEY 2.DLL is responsible for handling various licensing tasks, such as verifying the validity of software licenses, managing license expiration dates, and enforcing usage restrictions set by the software vendor. It also encrypts and decrypts sensitive licensing information to protect against unauthorized access or tampering.
This DLL file is commonly used by software vendors to enforce licensing agreements and prevent unauthorized use or distribution of their products. It helps in ensuring the legal and authorized use of software applications by verifying the presence of valid licenses and validating their integrity.
PSIKEY 2.DLL is an essential component for software applications protected by the PSI system. It is loaded into memory when the protected software is launched and works in conjunction with other components of the licensing system to provide secure and reliable licensing functionality.
