If FFF/SeVen did indeed break ECDSA on
sect163k1 they should (in theory) be able to generate licenses with LM_STRENGTH_163BIT considering the following from the flexlm headers
Code:
#define LM_PUBKEY_CURVE113BIT sect113r1
#define LM_PUBKEY_CURVE163BIT ec163a02 // (a.k.a sect163k1)
#define LM_PUBKEY_CURVE239BIT ec239a03 // (a.k.a. sect239k1)
IMHO it is much more likely that Rarlabs made a poor choice of privkey/pubkey or have other implementation problems whereas
Macrovision/Acresso/Flexera bought their ECC/ECDSA-implementation from Certicom, a respected(?) company dealing exclusively in high security software products...
So to answer your question: I personally don't think we are going to see keygenned flexlm CRO/TRL SIGN2 licenses anytime soon ...
