I would like to leave a copy of the BIP39 words with a person of my trust.
Where is the safest place I can download the BIP39 file?
Having digital copies of your mnemonic set is always discouraged due to security issues.
However, if you really want to give a digital copy of your recovery phrase to a person I'd personally suggest to take a picture of the recovery phrase, encrypt the picture, compress the encrypted picture and finally encrypt the compressed file again.
Please take this suggestion with caution since I'm not a security expert.
Found it! It's in IOG's
cardano-crypto repository. Have a look:
You can download this website to a folder https://iancoleman.io/bip39/ and generate a BIP39 code on a clean computer not connected to the internet.
With that site, you can generate as much as you want. or just buy a nano ledger x. Far easier.
