Setting up Blockstream Jade

[Pmalek]

I haven't used Krux for creating a seed.  I already have seeds that I made with a Blockstream Jade.

Looking at it from the surface without going into too much details, I prefer the Jade to generate my new seeds rather than the Krux. I could also do it with a Trezor or a Ledger, but that's not recommended and defeats the purpose of an airgapped hardware wallet. Getting the entropy from dice rolls in combination with a passphrase for added security is also a good option.

You mean in general, right?
Because you can't do that in Jade. There isn't a feature to import custom entropy, like there is for example in BlueWallet, where you can import dice rolls or coin flips etc.

There is an advanced feature in Jade that allows you to generate your seed using dice. It's a bit complicated and isn't your average dice rolling method. It requires three die: two 16-sided and one 8-sided. There is a table that corresponds to words depending on the results of the three rolls. You can take a look at it here: https://help.blockstream.com/hc/en-us/article_attachments/21328564164505

After you have done that, you can import the words into Jade and let it calculate the final word. It works both in the stateless and the standard Jade signing mode.

Ok I think I have undrestood.
So, basically, you need to:
1. throw the dice
2. manually convert the results into BIP39 words using their helper table.
3. press calculate in order to calculate the last word (it will internally use SHA256 etc).
Sounds good.

Let me add another way, with 1 classic 6-sided die.

1. Get 1 classic 6-sided die.
2. Convert the throw into bits like this: 1 = 00, 2 = 01, 3 = 10, 4 = 11, 5 = 0, 6 = 1
3. Generate 11 sequences of 11 bits each.
4. Convert each sequence into decimal.
5. Find the corresponding word in bip39 wordlist table.
6. Import the words in Jade, as mentioned in your list.
7. Jade will calculate the checksum for you.
8. Write the final seed phrase down and back it up at twice.

I am not sure one die is good enough to generate random enough entropy. It could have a tendency to roll one number or more of them than the rest. The more die you have for this purpose, the better.   

2. Convert the throw into bits like this: 1 = 00, 2 = 01, 3 = 10, 4 = 11, 5 = 0, 6 = 1

What's the source for this conversion system? Seems a bit too technical for me to do without a proper guide to explain the ins and outs. I am guessing it would require an airgapped wallet to do the work offline in a safe manner.

To be honest, I have seen it somewhere, but I will disappoint you because I can't remember where.

The conversion could be even easier though.
Like this:
1 = 0
2 = 0
3 = 0
4 = 1
5 = 1
6 = 1
