Default Approach for recent FlexLM daemons?

Hi!

For the last years, I relied on Arlequim's old but great working generic ECC patcher. Unfortunately, many vendors now use more recent FlexLM versions and that tool isn't effective anymore.

I'm now trying to achieve the same result by analyzing the vendor daemon using IDA but I have no clue how to find the _l_pubkey_verify() function (if it's still used).

Target uses FlexNet v11.15.1.0 build 225974 (ipv6) i86_n3 (lmgr.lib) 32 bit. I do know the names of the features and can build correct .lic files (apart from the SIGN-part, of course) for the daemon.

What approach would you recommend? Should I try to find the FlexLM SDK of that exact version? Or are there any FLAIR-Signatures available?

Thanks for any help!
