Base58 encoding/decoding package in Go

This is a Go language package fo encoding/decoding base58 strings. This package supports multiple encodings.

tv42/base58 is an existing implementation. But I do not like what the package provides; the interface of the package, the command-line interface, the pull request of configuring the encoding is not merged for months, leading zeros and empty string are not encoded correctly. So I created a new package and command line interface.

Package Usage

package main

import (
	"fmt"
	"os"

	"github.com/itchyny/base58-go"
)

func main() {
	encoding := base58.FlickrEncoding // or RippleEncoding or BitcoinEncoding

	encoded, err := encoding.Encode([]byte("100"))
	if err != nil {
		fmt.Println(err.Error())
		os.Exit(1)
	}
	fmt.Println(string(encoded))

	decoded, err := encoding.Decode(encoded)
	if err != nil {
		fmt.Println(err.Error())
		os.Exit(1)
	}
	fmt.Println(string(decoded))
}
