flexlm : identify the attribute in lc_set_attr

Hello, I am trying to identify the proper attribute set in this application :

The license file has this format:


INCREMENT <feature> <daemon> 2005.12 28-sep-2006 3 \
8D81D6CB16C7193E0828 VENDOR_STRING=^1+S&PID=12345678&

Here, the PID=12345678& is actually encrypted version of some string. For example,
If I want to install this application, not only will it ask for the license, but it will also ask
for the PID in the vendor string. If I put say "tree" it will then encrypt it and if that encrypted
version is the same with 12345678&, only then I am able to install the product.

I am trying to bypass this function but I need to identify the attribute that is set in lc_set_attr.
At least, that's what I think I must do first. So, any suggestions...
