RNG in keygen

[chickenbutt]

I'm looking for an example keygen in any language that has RNG used in a functional part of the key.

Are you talking about specific solutions for serials that somehow check randomness?

Or just a plain old LCG to generate random characters/numbers?

for generation, I know it's used for key generation in a lot of systems like RSA, but was wondering how it could generate key-data and be checked, or anything. It'd be cool cause big number calculations couldn't really be used to reverse it like with everything else in use.

EDIT: I actually knew this was impossible, just wanted to see if someone would try to answer ^^
