question

Hi @ake ,

I found this resource which may be helpful:

Communication encryption between lmgrd, vendor daemon and client - Community (flexera.com)

In case that link changes in the future, here is the important bit:

the communication between license server and client is in encrypted format... FNP has implemented different avenues to make communication secure...

While it does not specifically state it uses TLS, the article does go on to explain what they do to secure communications between a client PC and a license server using lmgrd:

=>There is secret key shared on the fly, in between License server and vendor daemon for their important message exchange. These messages are authenticated on both sides with help of secret key.
=>Client performs the handshake before important communication (like checking out feature license ) with the license server. As a result, further communication on same socket will be encrypted.
=>For data integrity check, checksum is generated on the basis of secret key which both client and server contains. The authenticity and integrity of message will be checked with checksum on the other side.
=>FNP also incorporated some other proprietary algorithms for message information authenticity.

This resource is dated Dec 01, 2020, and mentions that additional encryption work is ongoing, without giving any release date. I haven't been able to find further information.

I hope that helps!
