API

encode(input)

input must be a Buffer or an Array. It returns a string.

example:

const bs58 = require('bs58')

const bytes = Buffer.from('003c176e659bea0f29a3e9bf7880c112b1b31b4dc826268187', 'hex')
const address = bs58.encode(bytes)
console.log(address)
// => 16UjcYNBG9GTK4uq2f7yYEbuifqCzoLMGS

decode(input)

input must be a base 58 encoded string. Returns a Buffer.

example:

const bs58 = require('bs58')

const address = '16UjcYNBG9GTK4uq2f7yYEbuifqCzoLMGS'
const bytes = bs58.decode(address)
console.log(out.toString('hex'))
// => 003c176e659bea0f29a3e9bf7880c112b1b31b4dc826268187
