-snip- but have the script, if i use 24 words a lower entropy with the wallet applications that use bip39? i mean every 24 words have same entropy?
I don't get what you mean but, in simple words: with the 24words that you've created with that tool wont restore the same address it generated if imported to any wallet.
That means the script is not a good way to generate a wallet that i use for finanical stuff?
If you use the tool in a secure environment like in an Air-Gap machine, then using the private key is secure enough.
But based form the OP and title, it's not the tool that you're looking for.
