FlexLM keygenning question

Interesting low-level stuff, operating system related issues, packer/vx acrobatics, drivers and non-newbie programming in general, including win32 assembly and whatever else.

FlexLM keygenning question

Post by john »

Hi everybody,
I have a FlexLM 10.8 target, have a valid license with hostid=flexid=dongle and I want to make a keygen for a hostid=ANY or whatever. I have found seeds using the structure zeroing method, have built the lmcrypt.exe, but the keys it generates are not correct. Valid license has a 20 chars key, but lmcrypt generates 16 chars in 7-th version compatibility and 20 chars when 20 zeros are defined in template. But it is not correct. Maybe prog uses some additional crypt. How can I figure it?

john,the vendor use the permutation tables... You need to dig inside the crypt_filter and the xor_vals.
