I have one with 9 characters.

Yep. See: https://github.com/katmagic/Shallot https://github.com/lachesis/scallion > Anyway. The GPU's are just getting stronger these days!

Onion addresses use Base 32. The probability of bruteforcing a custom domain is - I think - 32^n, n being the amount of characters you want to brute force. complete 16-characters-long onion domain you need about 32^16 tries. This is probably more complicated since there's actually a 1024-bit-RSA key behind this domain. While this is certainly not easy to brute force yet, next generation onion services will be quite a bit more secure in this regard. See below. > Question 2: Will the next generation hidden services get longer onion names? Yep, about 52 characters. -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
