View Full Version : FLEXLM Need Help

January 21st, 2014, 03:42
Hello, i'm from Russia so sorry for bad english.

I have software protected by FLEXLM v.

I have old license file:
. FEATURE Service vendor_name_here 42 02-may-2011 uncounted FDEC386242A68AF23EB5 \

I also have seed1 and seed2 and FLEX SDK 7, but when i put all my data in lm_code.h and run genlic32.exe i recieve only 12-digit key (i need 20-digits)

What is my problem? Wrong seeds? or i should use sdk 10.8? if so please help me find it

Ok, now i can compile sdk 7 and get 20-digits key. But that keys don't work on my software

I'll try 11.4 SDK, but there is no ENCRYPTION_SEED here in lm_code.h, only LM_SEEDS. Without it SDK don't compiles.

Please tell me where can i read about the difference between ENCRYPTION_SEED and LM_SEEDS, and where is my mistake?

last flexlm like 11.x not use ENCRYPTION_SEED's. only LM_SEEDS 1/2/3 for sign license. try to start from "Programming Reference for License File–Based Licensing FNP-11[10]-PRLF01"

Thank you, I read this article. My problem is that, although the vendor version is 10.8, it only contains ENСRYPTION_SEEDS (got them by flexlm-7-x-11-4-seed-extraction.pdf), and uses 20 digit keys. I tried to create 12-digits keys in SDK 7, and then run "lmcrypt -verfmt 5 -longkey", but this keys dont work.

Since the example license contains no "SIGN=" attribute I would not expect it to make use of LM_SEEDS.
I think this vendor may make use of a user crypt filter in license generation.
