Good or Bad experiences with CryptoLicensing? [clo

问题:

I'm planning to buy CryptoLicensing but before buying it I'd like to get some feedbacks if anyone tried it before. Also it'd be interesting if anyone cracked it or spotted an easy hack against it.

I've seen some other SO questions regarding the choosing a .NET licensing component but if you currently happy with another component it'd be nice to hear your experience. It's just quite hard to nail this without going through a long trial.

回答1:

I bought the licensing and obfuscator products from LogicNP and I'm quite satisfied.

CryptoLicensing:

The good:

• good value for your money. I didn't pay through the nose and the product accomplished what it needed to
• good flexibility - I could generate licenses to reflect all sorts of settings and fairly easily too. Also seeing all the features in the license generator interface gave me a number of good ideas for different licensing schemes for my product
• ease of use: setting this up wasn't too difficult. I was also surprised at how easy setting up an online license service was for someone like me who has little experience with ASP.Net (the license service is necessary for eCommerce sites and for activating licenses on a fixed number of computers per license)
• good customer support - I tried to wait until I was absolutely stuck before bothering them but they get back to me fairly quickly

The Bad (or rather not quite as good as I'd like):

• the documentation could be a little clearer at times. All major topics are covered and some of the trickier areas are covered somewhere (either in the help file or the online Knowledge Base) but I wish there was more depth in the documentation so I didn't have to hunt around. I did have to figure out a few things on my own which the documentation could have covered.
• like the documentation, the license generator UI could stand to be tightened up a bit. But I suppose the company could triple the price to be in line with the industry and give me a product that was far sexier but I like what I got.

CryptoObfuscator

I don't have much experience with trying to reverse engineer .Net programs so I can't comment on how secure it made my product. Obfuscation will never be perfect but it at least hinders most hackers enough to get them to give up. Like CryptoLicensing, CryptoObfuscator's documentation and UI could be tightened up a bit but I got good value for my money. What I really like is that once I set up the obfuscator for .net solution , I never have to think about it again other than to enable or disable the obfuscator from within Visual Studio.

In general, there is no such thing as an uncrackable system, if anybody claims this, they are ignorant or lying. Your aim should not be to look for an uncrackable system becuase such a system does not exist.

Your aim should be to use a easy-to-use, affordable system which offers reasonably strong protection, so that you do not have to spend time on the licensing/obfuscation part of your software but instead can concentrate on the core functionality of your software.

回答3:

I was also looking at it, but it seems like it has been cracked, and easily too. The ease of the bypass makes me wonder if Crypto Licensing spends more attention on marketing than on the product.

The bypass also works on the Crypto Obfuscator security product.

The code is here: (http://board.b-at-s.info/index.php?showtopic=7451 or http://webcache.googleusercontent.com/search?q=cache:x6Viykf521sJ:board.b-at-s.info/index.php%3Fshowtopic%3D7451+black+strom+cryptoobfuscator&cd=1&hl=en&ct=clnk&gl=au)

We are just starting out with CryptoLicensing so I can't give your question a direct answer.

But I think it's worth saying that we have found their customer service very responsive. We got good, timely replies to emails and they went the extra mile with one particular issue we had.

回答5:

I've been using CryptoLicensing for over a year now and have found it to be a very good product with a good price point. There is a bit of a learning curve, but their documentation is good so this should not be a problem. I also agree with @hawbsl above that the company provides good timely email support.

回答6:

Support is slow. Documentation reads as it has been obfuscated as well. the UI is counterintuitive. The license service requires a lot of manual configuration + extra programming... E-commerce integration only works partially... No one notifies the user/buyer of generated license, you need to write code for this yourself.

I wouldn't believe the few negative pieces of feedback before buying it myself.. since there are a lot of big names marketed on the site + when you look at the features there are a ton of them...

I bought the Enterprise version and other tools from logincp together thinking I was buying a complete system. Unexpectedly, the Only thing I'm happy about is crypto-obfuscator.

All the rest requires a lot of work to set up. I've switched to a cheap php licensing system that I was able to code in just a few days while with cryptolicensing I was already a week further without having the system set up...
