Create your very own .onion addresses

prepare

Make sure your computer is updated:

sudo apt update -y && sudo apt upgrade -y

Now get all required packages

sudo apt install gcc libsodium-dev make autoconf git -y

mkp224o

Now we will use a practical tool made by cathugger. Download it and get into the new folder:

git clone https://github.com/cathugger/mkp224o
cd mkp224o

Now let's configure and compile your program

./autogen.sh
./configure
make

To configure the programm for your need you can list all possibilities with ./configure --help. For example you could run ./configure --enable-amd64-51-30k (if you got the required hardware).

Right after that you can create your own address:

./mkp224o <filter1> <filter2>

You can choose your own filter options as those filters are the first characters of your address. All created links are saved in a subdirectory "/.onion"

To copy the address into your TOR folder you can simply copy it

sudo cp -r filter1 /var/lib/tor/hidden_service

Length of Addresses

New .onion addresses at v3 version require a length of 56 characters and end with '.onion'. To create an address the program generates keys until a fitting one, with your filter option, is found. The longer the wanted filter length is, the longer the program has to work.

As a example this table was created on a computer with 16 kernels at 4Ghz each:

filter length	1 Thread	2 Thread	4 Thread	8 Thread	16 Thread
1	0,101s	0,102s	0,102s	0,102s	0,102s
2	0,102s	0,102s	0,102s	0,102s	0,005s
3	0,101s	0,101s	0,101s	0,103s	0,103s
4	0,302s	0,102s	0,102s	0,102s	0,108s
5	25,622s	3,404s	2,203s	7,907s	2,804s
