How hard is it to guess a license-key?
There’s two approaches to this: guess the license-key, or guess the ENCRYPTION_CODEs. Both of these are roughly equal in difficulty, and involve guessing 2 32-bit numbers. Assume you can guess, and test, 4 billion numbers (one of the 32-bit numbers) per minute. (This is an extremely optimistic estimate, but useful for conjecture). It will then take 4 billion minutes to guess all possible numbers. On average, you’d hit the right number halfway through, so, assume 2 billion minutes. Let’s see, there’s 1440 minutes per day, roughly 525600 minutes per year, 525.6 million minutes per century. OK, it will take a while. In reality, testing ONE license-key, particularly for interactive applications, can take a minute or more.
