New IP addresses.
« on: October 13, 2001, 04:17:00 am »
It's general discussion so I'm exercising my right :smile:

I've looked through the code of the new hiddenhost...and well I can't make heads or tails of it.  I can make it to as far as the array of hex values (i think that's what they are).  

Anyone wanna take a gander at explaining them to me?  i.e. step by step?  I understood the older ones a bit more...

Thanks in advance..

Hehe, well, where to start? :smile:

Ok, the concept itself was deviced by a few smart chaps over at Roxnet, originally for ******IRCd. Unlike the old one which used a very simple hashing, the new one is far more complex, and would take quite a few hours for a dedicated cracker to decrypt. This will be made even more difficult as in the near :badword:ure the 3 keys used for the hashing/encrypting will be user definable for each network. Which renders then as 3 secret keys which will make that networks hiddenhosts unique, aswell as making the networks hiddenhosts harder to crack as the 3 values used are unkown to the cracker.

Now, as for the system itself.
Example host: LifeStream.Shadow-Realm.org
Example IP: 195.159.32.103

Now, in the event of the IP resolving you would see a hiddenhost like this:
xxxxxxxx.xxxxxxxx.xxxxxxxx.xxxxxxxx.Shadow-Realm.org

The xxxxxxxx represents a hexadecimal value which a hashed value of the IP. If you where to magically uncrypt the hiddenhost you would see:

103.32.159.195.Shadow-Realm.org

Plans are to alter this system a bit further to make it a bit more userfriendly in terms of looks and make it look like:

Hashed/Encrypted:
xxxxxxxx.xxxxxxxx.Shadow-Realm.org

Automagically uncrypted:
103.32.Shadow-Realm.org

The whole idea behind the system is to add a basic level of protection, there is no real point in trying to archive an unbreakable hiddenhost because its impossible. Someone determined to get your IP will manage to do so in one way or another if he have a lil knowledge about you and where you venture on the net.

Now, if the IP didnt resolve, you would be left with a hiddenhost looking like:

xxxxxxxx.xxxxxxxx.xxxxxxxx.xxxxxxxxX

Which is the hidden IP, reversed. ie:
103.32.159.195X

Its being considered to alter this system slighly aswell, but its not been decided yet.

Hope this helps to shed some light :smile:

No IP is secure but these Encyption protects the user from getting Scaned i have seen some Scripts on *****Net.... they scan all users in the Channel on join for Trojan Standart Ports.

Exactly, and that is what its meant to deter, im not really worried about mr expert cracker who is determined to take me down in one way or another, because he will most likely know enough to try and track my IP down trough other means. If someone wants you down bad enough, this wont protect you much as it can be cracked if your willing to spend some time doing it, but it does protect users from easy and more or less random DoS attacks, and protects them from easy probes for say Sub7.
