lmgr326a.dll )Load up the target EXE and set break points wherever the lc_init()function is called.Run your target until it breaks.Looking at the prototype for lc_init in lm_client.h we see:lm_extern API_ENTRY lc_init lm_args((LM_HANDLE_PTR job, LM_CHAR_PTR vendor_id, VENDORCODE_PTR vendor_key, LM_HANDLE_PTR_PTR job_id)) job will be NULL as it's the first one.job_id will be a pointer for the job structure to be filled by thefunction.The things of interest for us are the vendor_id and vendor_key.Vendor_id is just a text string.Again looking in lm_client.h we see:typedef struct vendorcode5 VENDORCODE5, FAR *VENDORCODE_PTR #define LM_MAX_BEH_VER '06.0'In the above structure, data = encryption seed 1 XORed with vendor key 5data = encryption seed 2 XORed with vendor key 5keys = vendor keys 1 to 4behavior_ver = string containing FlexLm version ( in this case = '06.0' )So all the stuff above will be pushed onto the stack prior to calling lc_init.GENT SUPERVISOR 3 S3 Custom Key GeneratorCustom Keygens Pinnacle. S+H details how to crack it, or ask FlexLm.Once you've got it installed the main files of interest are:lm_code.h : This is where you want to put in all the target key informationlm_client.h : Contains useful function prototypes and error codesGenLic32.exe : this program checks the keys and generates licenses for you.I'd also recommend reading the html manual.2) Find the easy information using lc_init()=Using W32DASM, decompile your target application and the vendor daemon DLL it uses ( e.g. The above program ran on Linux, but my target ran on Windows 95/NTThe aim of this tutorial is to expand on some of the ideas in thefirst tutorialand to detail the differences encountered on the PC.ġ) Get hold of the flexlm programmers kit=This is obtainable from needs a key to decrypt the file.
