base58 A Fast Implementation of Base58 encoding used in Bitcoin

Fast implementation of base58 encoding in Go (Golang).

Base algorithm is copied from https://github.com/trezor/trezor-crypto/blob/master/base58.c

To import library

	import (

Example

package main

	}

	// If a base58 string is on the command line, then use that instead of the 4 exampels above.
	if len(os.Args) > 1 {
		exampleBase58Encoded = os.Args[1:]
