In light of the recent happenings with Ledger, I have become concerned about the security of my seed phrase on my device, Nano S Plus. Even though the issue doesn’t affect my device (yet), I have been researching other methods of securing my Bitcoin crypto assets.
I came across a few videos showing seed generation using Ian Coleman’s BIP39 tool and was quite interested in using this option as an alternative for seed generation.
On the first video, the content creator recommends to use 6 sided dice and to roll 100 times to create 256bits of entropy (using the Base6 entropy value option). I assume it converts to binary at the end to create the 24 word seed.
On the second video, the host recommends to use the same 6 sided dice, but instead to roll 256 times to result a binary (base2) total 256bits. He says if the dice rolls 1,2, or 3, the result will be binary “0” and if it’s a 4,5, or 6, it’ll be binary “1”.
Hopefully, I explained that right. What I would like to know is if the totals both come to 256bits, regardless of methods, is the security / entropy the same quality as each other?
If using the second option – 256 rolls direct to binary using the 1,2,3=”0″ and 4,5,6=”1″, would it make any difference to overall entropy if I did the following:
Words to generate (1 – 8): 1,2,3=”0″ and 4,5,6=”1″
Words to generate (9 – 16): 2,3,6=”0″ and 1,4,5=”1″
Words to generate (17 – 24): 3,4,5=”0″ and 1,2,6=”1″
What are your thoughts on this? Any input is appreciated!
