ssh-ed25519-bip39

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).

Usage

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

TODO

Add passphrase protection for BIP39 backup?

Misc

No guarantees, use at your own risk.

I don't plan to support/improve this code (but will accept PRs).
