Here is what I would do:
Unlock DR, add the back door and change the needed key. That way you can tell people to re-DL it, and give them the new key. If they tried that old version it wouldn't work.
Exactly. This relies on obtaining/destroying the original pass-key, though, since that original would still work on the original version of the algorithm that's already out there on the Internet. Once you've destroyed the original pass-key, those existing versions out there are useless, so anyone wanting DF would need to download your new version (and its new pass-key).

it doesnt matter anyway, it was a virus, not a code for them to break, and there was no pass key, only the kill code

All he had to do was insert the back door and then sell the company the key and the code in a bundle. The companys might get suspicous if you asked everyone to re-dl the code. and yes it was just a virus, but at that point in the book nobody knew it!

Absolutely agree. It came to me as well while I was reading the book.
That's the danger with those books (or series like 24) which contains a surprise at every chapter. At the end, you realize that there were simpler solutions... but less impressive

I agree. After all DF was no unbreakable code; it was just a virus.
Anyways, the kill code was really good. The number three(3) seemed pretty easy but i think all expected a difficult and cryptic number. So three(3) was pretty unobvious but all the more interesting.
I especially liked the connection with Tankado's fingers.
