Monero/Aeon offline wallet generator
This page generates a new Monero or Aeon address. It is self contained and does all the necessary calculations locally, so is suitable for generating a new wallet on a machine that is not connected to the network, and may even never be. This way, you can create a Monero or Aeon wallet without risking the keys.
The repository contains 3 different editions:
I wanted a way to generate a Monero wallet from dice (d6) rolls. Previously I did it by rolling d6 triplets and converting the resulting number (0-216) to a 2-digit base16 number (00 to D8). Repeat enough times, and you get the 64 char base16 string which can be used as seed and generate the wallet. However, I was not happy with this approach because this way some entropy is lost. Also, I didn’t want to just hash the rolls because that’s one way conversion. Instead, the idea is to just get a big enough base6 number, convert it to a base16 number and that’s it. No crypto wizardry but pure pyhsical randomness, actual dice rolls are the seed.
The base6 number “has” to be exactly 98-digits, and the first digit can be either 0 or 1. This is achieved by performing modulo 2 on the first roll only, so the even roll will result in 1 and odd in 0. The biggest number you can represent like this is:
in base6, equivalent to rolling:
the l is:
and already, any seed generated is divided by the l and remainder used as the private key, so any number bigger than l is a waste of rolls. The above number (
155...) is about
0.835*l, so we’re almost using the entire domain of possible seeds, mapped 1-to-1 to your dice rolls!
Similar to the dice version, but the conversion is from base2 to base16. It accepts only numbers 1 and 2, and requires 252 flips. This is cool because if you play around you can directly see in the seed where it was changed for each flip, since any group of 4 flips will correspond to some letter in the seed.
This version will show QR codes for both address and privte keys. In addition, it should be nicely foldable when printed.
