base58check

JavaScript component to compute base 58 check encoding. This encoding is typically used for crypto currencies such as Bitcoin.

Install

npm i --save base58check

API

string encode(data, prefix = '00', encoding = 'hex')

data must be a Buffer or a string. It returns a string.

example:

const base58check = require('base58check')
 
const data = '086eaa677895f92d4a6c5ef740c168932b5e3f44'
console.log(base58check.encode(data)) // => 1mayif3H2JDC62S4N3rLNtBNRAiUUP99k

{ prefix, data } decode(string[, encoding])

string must be a base 58 check encoded string. Returns a Object for prefix & data.

example:

const base58check = require('base58check')
 
const address = '1mayif3H2JDC62S4N3rLNtBNRAiUUP99k'
console.log(base58check.decode(address))
// => { prefix: <Buffer 00>, data: <Buffer 08 6e aa 67 78 95 f9 2d 4a 6c 5e f7 40 c1 68 93 2b 5e 3f 44> }
 
// if using encoding
console.log(base58check.decode(address, 'hex'))
// => { prefix: '00', data: '086eaa677895f92d4a6c5ef740c168932b5e3f44' }
