usually, the vendor do not use the pubkeyinfo when they protect their softwares. but I find a new software which is protected by flexlm 9.2 using pubkeyinfo. I have found their VENDORCODE ,EN_CODE, CROCODE, also generated a license file. this license file active the vendor server very fine, but software can not run because of the pubkeyinfo. I copy the pubkeyinfo from venfor_LM.exe to my code, also I get the wrong license file. how do the flexlm use the pubkeyinfo (see VENDORCODE7 struct), I search the inet, cant find any informations. could some spidermans give me some useful advices? thx in adv.
