Title: [INCONSISTENCY] BIP39 Mnemonic - Ian Coleman's website vs learnmeabitcoin Post by: apogio on March 03, 2024, 11:39:40 AM Hello, I am not entirely sure if this is the right place to post it.
I have noticed an issue (inconsistency), in BIP39 mnemonic generation, between Ian Coleman's website (https://iancoleman.io/bip39/) and LearnMeABitcoin (https://learnmeabitcoin.com/technical/mnemonic) I have tried to generate a mnemonic, by feeding these websites with my own entropy (in binary format). They produce different mnemonics. In Ian Coleman's website I made sure to select a 12 word length mnemonic. So, naturally, I wanted to try and find out what is wrong... I generated the following entropy: Code: 10010100101010110101111110001011000101000011110111100011101111000001011110010101101011010000011000011111111011110010000000111001 This entropy provided the following mnemonics: Ian Coleman's website: Code: steel tiny neither hospital waste off essence cruise leaf antenna dawn bracket Code: net foot tissue chronic taste task furnace remember alcohol youth siege indoor Unless I am missing something here, do you have any thoughts?

This is from Ian Coleman: Quote 1001010010101011010111111000101100010100001111011110001110111100000101111001010 1101011010000011000011111111011110010000000111001 You posted this Quote 1001010010101011010111111000101100010100001111011110001110111100000101111001010 1101011010000011000011111111011110010000000111001 They are both the same.

How did you produce it in Ian Coleman's site? When I enter the entropy that you mention it produces a different seed phrase... Perhaps I am doing something wrong, that's why I ask. EDIT: I have been using the "12 word seed length" from the dropdown. If I enter the "use raw entropy (3 words per 32 bits)", it produces a valid seed phrase. Sorry for that, I thought it was the same, because I want a 12 word seed phrase... |
