How well does CrypKey protect against computer hackers who want to defeat the copy protection?
For CrypKey Instant users, a variety of techniques are employed to complicate the hacker’s job. Although we can’t reveal them all, a short list includes: 1) Random Encryption – Hackers are most dangerous if they can make one patch that will work on all programs protected by a particular tool. CrypKey behaves differently on each application so that a hacker’s efforts on another software protected by CrypKey will not apply to yours. 2) The Math Challenge – Often the reason for why a program can be hacked is that the security function returns a simple ‘0’ or error number, so it is easy to rewrite the binary code to just return ‘0’. CrypKey has a function that returns the result of a complex randomized calculation only if the program is authorized to run. The programmer can reproduce the calculation and check for correct results, but the hacker has no way of reproducing the calculation, since it is based on secret encrypted numbers that are customized to each CrypKey customer. 3) Encryptio
