Software cracks usually only work for a single version of a particular application, sincethe application code itself is modified to bypass any license checks (meaning a softwareupdate often requires an updated crack for the new application code.) Distributing acracked version of an application falls on the bad actor.
The other major attack vector is known as a software \"keygen\", which is much more ominous. Asits name may imply, a keygen is a form of software, often a separate program or webpage, thatgenerates valid license keys, i.e. a key-generator, or \"keygen.\"
Some applications will have a central point in the bytecode where this check happens, but othersharden their system by inlining the license key checks, making the work of a bad actor wanting tocrack the software much, much harder. But licensing is all essentially the same: it's a seriesof conditionals.
But remember, a crack != a keygen, so your application's licensing always runsthe risk of being circumvented via code modification. But license keys cannotbe forged when you utilize a licensing system built on modern cryptography.
License keys are the defacto-standard as an anti-piracy measure. To be honest, this strikes me as (in)Security Through Obscurity, although I really have no idea how license keys are generated. What is a good (secure) example of license key generation What cryptographic primitive (if any) are they using Is it a message digest If so, what data would they be hashing What methods do developers employ to make it difficult for crackers to build their own key generators How are key generators made
However, despite being broken up into steps, this falls prey to the same methods of cracking used for the normal process. The process used to create an activation key that is checked against the original CD key was quickly discovered, and generators that incorporate both of the keys were made.
The answer is simple but technically challenging: digital signatures using public key cryptography. Your license keys should be in fact signed \"documents\", containing some useful data, signed with your company's private key. The signatures should be part of the license key. The product should validate the license keys with the corresponding public key. This way, even if someone has full access to your product's logic, they cannot generate license keys because they don't have the private key. A license key would look like this: BASE32(CONCAT(DATA, PRIVATE_KEY_ENCRYPTED(HASH(DATA))))The biggest challenge here is that the classical public key algorithms have large signature sizes. RSA512 has an 1024-bit signature. You don't want your license keys to have hundreds of characters.One of the most powerful approaches is to use elliptic curve cryptography (with careful implementations to avoid the existing patents). ECC keys are like 6 times shorter than RSA keys, for the same strength. You can further reduce the signature sizes using algorithms like the Schnorr digital signature algorithm (patent expired in 2008 - good :) )
In the past, I've used Treek's Licensing Library many times, because it fullfills this requirements and offers really good price. It uses the same license protection for end users and itself and noone cracked that until now. You can also find good tips on the website to avoid piracy and cracking.
It is an all-encompassing tool and it merges Microsoft2013 with others that sync the libraries and attributes. If a user desires to use the product key for Microsoft Office 365 with some issues, then he must need the right key that fits the latest version of the software. One can also use the crack version as it is for a lifetime; however, it is always recommended to use licensed products and not go for any short cuts. 59ce067264
