FlexLM still number 1 when ranking “uncrackable” software protection

you are not right... one bytes patch and passed checkout license for long SIGN. or use fake public key for client/daemon

I agree.
There used to be a saying that FlexLM is for "honest" companies and people who want to honestly keep track of the licenses they purchased and use.

For crackers and pirates like us who do not care about licensing software, FlexLM is one of the easiest protections to crack! :D
This protection was always cracked right after release! :cool:

Oh ok, well I’ve got to learn about it then :) ; what do you think about Viper from back engineering ?

Tyro, you said in another thread just now how important license restrictions are and that you must follow them. Now you are saying you don't care at all. Are you teaching a masterclass in hypocrisy?

Properly implemented latest versions of Sentinel Pro dongle (AppOnChip, etc) have not been fully cracked yet.
Nearly all the other protections have been completely cracked.

Very little has change for flexlm the past few years.
You can start with darsy tuts. A good starting point.

Despite the claims made the vendor, the overall process to crack it has not changed much over the years.
All the required tools and techniques are available in this forum.
If you have any questions, I will be happy to help.

Never heard of viper. Any real-life examples?

Tyro, several things have changed, likely you should have a look at notably "New Obfuscation Mechanism for Client and Server Communication"

Tyro, I understand that you are unfamiliar with FlexLM.
See post 107 by master FoxB. It can be cracked very easily even today, if you know how. Whatever the vendor claims are all BS!

Tyro (and we can see from your registration date that you are the tyro, you dont seem to know what it means), the variety of cloud and web related security features are not clear as to whether anyone has found a target using them or defeated them. The underlying scheme being weak, maybe we don't expect much.
