Function KG_VerifyRegistrationInfoW

KG_VerifyRegistrationInfoW is used for verifying the registration information and extracting registration key parameters from unicode-based registration information. The function has one parameter - a pointer to the TKeyVerifyParamsW structure. Please note, the TKeyVerifyParamsW structure should contain secure parameters from the Enigma Protector project. These parameters are PublicKey, KeyMode, KeyBase and EncryptedConstant (see the Registration Features - Common panel, Information for Custom Generator box).

Return Values
