module base58

base58 encoding and decoding module

base58Module is a module used for Base58 encoding and decoding of data. Base58 is a combination of numbers and letters. It does not contain easily confused characters such as the number 0, the letter O, the letter I, the letter l, etc., and is less error-prone.

This module provides two methods encode: and . The method is used to Base58 encode the given data and return the encoded string. The method is used to decode the given Base58 encoded string and return the decoded binary data.decodeencodedecode

Here is base58sample code for the module:

var base58 = require('base58');

var data = "Hello, World!";
var encoded = base58.encode(data);
console.log(encoded); // => 'StV1DL6CwTryKyV'

var decoded = base58.decode(encoded);
console.log(decoded.toString()); // => 'hello world'
