Wrong. Did you ever hear of assymetric encryption (RSA, etc...) ? A CD key could be implemented as a digital document signature, for example.

But with source, the server owner could simply change the code and recompile it to disable such checks... ;-)

Yes, but you're assuming that they did anything that sane. Remember the Elcomsoft case? The encryption that Adobe went to court to defend was a piss-poor implementation of the Caesar shift cypher.

Basically, we're seeing companies use the courts to do the job that should go to real cryptographers.

Unfortunatelly you can not create short activation code this way (short here is 12-24 characters i.e. 72-144bits: enough for symmertic encryption, way too small for assymetric).
