var out = bs58.encode(new Buffer(unencodedData, 'hex'))
console.log(out) // => 16UjcYNBG9GTK4uq2f7yYEbuifqCzoLMGS

input must be a base 58 encoded string. Returns an Array.

example:

var bs58 = require('bs58')

var address = "16UjcYNBG9GTK4uq2f7yYEbuifqCzoLMGS"
var out = bs58.decode(address)
console.log(out.toString()) // => 0,60,23,110,101,155,234,15,41,163,233,191,120,128,193,18,177,179,27,77,200,38,38,129,135
