Creating a 24-word list from the bip39 English word list, then packing it into 4 blocks and extracting them back.
How to use:
Source of the bip39 wordlist:
https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt
https://raw.githubusercontent.com/bitcoin/bips/master/bip-0039/english.txt
Prepare:
1. Install Required Python Libraries:
pip install cryptography pillow qrcode
2. Download the BIP39 English Wordlist:
wget https://raw.githubusercontent.com/bitcoin/bips/master/bip-0039/english.txt
create 24w.txt
