How about a vanity Whonix v3 onion?
Apparently it isn’t that hard to create a v3 onion address for something matching the first six characters you’d prefer - with a reasonably powerful PC it might only take 10s of minutes at that length.
Raspberry Pi estimates re: generation usking mkp224o (see Tor Onion v3 Vanity Address).
Vanity Characters : Approximate Generation Time
1 : <1 second
2 : <1 second
3 : 1 second
4 : 30 seconds
5 : 16 minutes
6 : 8.5 hours
7 : 11.5 days
8 : 1 year
9 : 32 years
10 : 1,024 years
11 : 32,768 years
12 : 1 million years
13 : 32 million years
14 : 1 billion years
15 : 32 billion years
…
So you could imagine generating something like:
whonixdebrkhllykiyiztbpg6fokecmzhxvj4buig5qss5m4wasn5yyd.onion
Why?
- brand recognition
- users/interested observers will have greater confidence in a more recognizable onion i.e. they’ll learn to recognise the first 10 digits or so (thus providing better security as a side effect)
- anybody trying in the future to mimic the Whonix v3 onion to X digits will have great difficulty e.g. once they try for 12 digits (?) or more that match, they are (probably) out of luck even with their supercomputers
- you can brag to your dev friends
Two options are still operational (at least):
- mkp2240: GitHub - cathugger/mkp224o: vanity address generator for tor onion v3 (ed25519) hidden services
- oniongen-go: GitHub - rdkr/oniongen-go: 🔑 v3 .onion vanity URL generator written in Go
How long will it take? (my bold)
mkp224o states:
Because of probablistic nature of brute force key generation, and varience of hardware it’s going to run on, it’s hard to make promisses about how long it’s going to take, especially when the most of users want just a few keys.
See this issue for very valuable discussion about this.
If your machine is powerful enough, 6 character prefix shouldn’t take more than few tens of minutes, if using batch mode (read OPTIMISATION.txt) 7 characters can take hours to days.
No promises though, it depends on pure luck.
You might enjoy playing with this? Not many have bothered with v3 vanity onions, so you could be a bit of a trendsetter in that regard.
