iota-seed

Generates secure IOTA seeds.

This package just uses officially recommended commands to generate a seed. If you don't trust this package or npm (and you shouldn't) you can execute the commands manually (see Security section). If you decided to use this package, check the downloaded source codes after npm install (node_modules/iota-seed). They should be identical to the ones from this github repository.

Usage

You can generate a seed using Command Line Interface:

> npm install -g iota-seed # check node_modules/iota-seed source codes after this
> iota-seed

YOURIOTASEED9999999999999999999999999 <- This is your IOTA seed

>

Or you can generate a seed inside of your program:

const iotaSeed = require('iota-seed')

let seed = iotaSeed() // <- This is you IOTA seed

Security

This package uses the next commands for seed generation:

Linux

cat /dev/urandom | tr -dc A-Z9 | head -c${1:-81}

Mac

cat /dev/urandom | LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1

Windows

It's not implemented and an error will be thrown if you try to generate a seed on Windows OS.

Unfortunately I don't know a really secure way to generate a seed on Windows OS. crypto.randomBytes is preudo random and powershell has it's own flaws.
