Create your very own .onion addresses

Preparation

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 <filter1>/<filter2>.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 (no GPU):

| 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 | | 6 | >2min | 1m12,853s | 4m18,385s | 53,527s | 52,261s | | 7 | 16h | 8h | 4h | 1h | 1h |
