Engaged on an opensource air-gapped crypto vault, by which I’ve the common technique of counting on OS to offer cryptographically safe random supply and use that to generate the mnemonic phrase.
Additionally want to present a guide choice of utilizing cube rolls or coin flips to offer your personal entropy and never needing to belief the software program to do it for you. Exploring how trustless it may be.
As, I perceive there are some bias related to cash & dices as nicely. They might are inclined to favor one or some outcomes greater than different. I’ve learn lots about offering your personal entropy supply and the way that can normally be insecure for those who by chance introduce some bias. However contemplating, I’m keen to go so far as flipping/rolling 256 instances to generate a 256 bit binary quantity, does that eradicate the bias?
If sure, then is it potential to make the most of much less variety of flips/rolls to generate much less entropy which is nicely verified to be safe sufficient for the aim of mnemonic era? Want to discover this feature as its merely lots of monotonous guide work for the extraordinarily cautious person & if its potential to scale back the burden with out sacrificing safety.
Once more, I’ve learn many statements by fellow folks on web however I’ve no means to confirm anyone’s declare therefore reverting to this group to chime in.
A few of the strategies I examine:
-
Utilizing a number of dices to successfully roll x dices in each try and do it quicker. Undecided how the order of studying dices matter right here. Noticed somebody mentioning they need to be learn in the very same order.
-
Strategy of blending coin flip together with 4 dices to make use of the supplied mapping to derive the phrases. I do not need to belief this. I’d very very similar to to reach at a random index for every phrase after which learn the worth at that index from the wordlist.
-
Utilizing Ionman’s BIP39 device, the way it exhibits the supplied entropy to be sufficient, it certainly required placing in 256 inputs (0/1) random values in there earlier than the safety validation message (mnemonic seems safer than it truly is) goes away. In order per that device, something lower than 256 flips/rolls is not safe sufficient. True?

Tips on how to interpret cube rolls: Then there’s additionally the query of deciphering the cube rolls. Do I take advantage of odd even numbers as 0 & 1 respectively or ought to I take advantage of half the vary of potential outcomes (1-3) as 0 or 1 and the opposite half vary as the opposite binary bit?
