regarding my previous thread about memorizing a 128/256 bit key,
I came up with the following idea to create Argon2id keys.
 
Now we only need to memorize our Diceware passphrase.
 
This task shoulb be carried out on an offline Computer.
 
I am using four Golang programs, called dwp (diceware passphrase),
dice2bip, leetspeak and argon2id, which you can find on my GitHub
page at:
 
https://github.com/stefanclaas/
 
Usage of leetspeak is optional.
 
First we start with dwp:
 
$ dwp -r 6 -d eff_large_wordlist.txt -p
Diceware number 1: 51534 - reselect
Diceware number 2: 25455 - envelope
Diceware number 3: 42252 - nuptials
Diceware number 4: 35561 - lapping
Diceware number 5: 26225 - expand
Diceware number 6: 24453 - earpiece
 
Complete passphrase: reselect envelope nuptials lapping expand earpiece

 
Calculated entropy: 77 Bits:
 
   number of positions: 30 (6 x 5)
   character pool: 1..6
 
| user15@o15:/tmp$ bc -lq
| 30 * l(6)/l(2)
| 77.54887502163468544431
 
Quote from <https://en.wikipedia.org/wiki/Diceware>:
 
| The level of unpredictability of a Diceware passphrase

Ok. now with a russian wordlist and a seperator. Would Eve
know that I used another Diceware wordlist, along with BIP39,
for creating an Argon2id key ...???

There are a couple of wordlists and one can create his own.

$ dwp -r 6 -d russian.txt -p -s "*"
Diceware number 1: 41644 - лад
Diceware number 2: 13132 - башкир
Diceware number 3: 11654 - аполог
Diceware number 4: 62335 - ужин
Diceware number 5: 56323 - суржа
Diceware number 6: 15314 - вагон

Complete passphrase: лад*башкир*аполог*ужин*суржа*вагон
