ssh-ed25519-bip39
Advanced tools
This command-line tool allows to backup Ed25519 ssh key as 24 english words (using BIP39 specification).
Obvious note: keeping these words in plain sight is insecure, because they are not protected by the password (see TODO).
Install the module:
npm install -g ssh-ed25519-bip39
Convert key to 24 words:
$ ssh-ed25519-bip39 key.id_ed25519
Restore key from 24 words:
$ ssh-ed25519-bip39 -r key.id_ed25519
Add passphrase protection for BIP39 backup?
No guarantees, use at your own risk.
I don't plan to support/improve this code (but will accept PRs).
