Project Timelock
"Time matters"
Timelock project

Well, we had so many essays on the "timelock dll" (now "vbox") protection schemes, that I had to systematize them. Hope somebody will help me sending a more complete 'synthese' tutorial ("how to handle our timelocks targets") that will cover, encompassing the essays you will find here, these very typical and quite frequent commercial protection dll-based schemes
As you will be able to read on my How to protect better pages, commercial protections are, usually, doomed by the intrinsic programming incapacity ('programming moroninness' :-) of all those that work for money instead than for pleasure (as anyone that has reversed a Micro$oft application will immediately testify).
This project, started long ago, has been 'taxonomized' on 12 December 1997
