Confirm key

Generate a short mnemonic from a key, to help with verbally confirming two keys are the same.

Works with any wordlist. As well as the BIP39 wordlist, a list of names is included, names.json. This can be useful for representing a peer in a user interface - if we don't know what to call them, derive a name from their public key.

Wanted: A culturally diverse name list.

Example

const confirmKey = require('.')
const crypto = require('crypto')

const key = crypto.randomBytes(32)
console.log(confirmKey(key)) // machine bag 

const names = require('./names.json')
console.log(confirmKey(key, { wordlist: names })) // Ewell Carlstrom

API

const confirmKey = requre('.')
const mnemonic = confirmKey(key, options)

Generate a mnemonic. Key is a buffer of any length, options is an optional object which may include:

• language - one of 'chinese_simplified', 'chinese_traditional', 'english', 'french', 'italian', 'japanese', 'korean', 'spanish'
• wordlist - a custom wordlist to replace the one from bip39. Should be an array of 2048 words.
• numWords - the number of words to derive (default: 2)
