Any experience with CryptoObfuscator or CryptoLicensing?

Question

I am in the market for a good (and cheap) .Net obfuscator. I am developing a .Net windows forms application.

I appreciated IntelliLock and SmartAssebly. I refused the first one due to lack of support (I sent two letters without an answer, without a support site, etc.). SmartAssebly looks pretty good, but too rich for my blood.

Has anyone used a CryptoObfuscator? Any good or bad experiences?

One day, I have you here, what about CryptoLicensing?

thanks

Answer 1

You can check Roy Osherove cryptography licensing message from last June. Roy is a VP R&D in the company I work for, and I appreciate his opinion, we seriously consider the use of these two tools in our future products.

Answer 2

I have been using CryptoLicensing and CryptoObfuscator for over a year now and have found that they are both very good products with good prices. Do not think that since the obfuscator is expensive, it should be better too! See this thread for a comparison of obfuscators:

I also use CryptoLicensing and I will talk about it as an obfuscator - it is good and has flexibility for different scenarios. It also comes with general scripting support out of the box.

The only thing I would say badly is that their user interface could do with a little Polish. They are also very powerful products with good documentation and good email support. I run obfuscator from my build process and it works.

User crypto obfuscator for several months - I find him pretty easy to use, and their email support service is very useful. The output is uninterpretable on ordinary tools like ILDASM, Reflector ILSPY or JustDecompile (but I'm not a hacker).

However, one day my Avast antivirus killed the obfuscator output (in the bud). He complained to Avast as a false positive, and he left with later updates. Suspect the Control Flow Obfuscation option, but you cannot be sure.

My software has an automatic update and creates an updated exe that can be blocked by AV. Thus, your customers may not receive updates, and new customers may not install, while the manufacturer of AV checks your claims.

It appears that if your software is code-signed, you will not receive such warnings: see this http://wyday.com/forum/viewtopic.php?f=1&t=21786

Hope this helps readers today.

The problem with this product is the price, if you go with a 12-month upgrade or license renewal, it will cost about $ 259 more than a $ 649 product. In addition, if you are doing research, in the past the product had several errors that made me wary.

Take a look at Babel.NET obfuscator. This free version is still very good and one of the few that does not block you on one machine if you decide to buy it. Perhaps this is the best I have found if you can get through the command line.
