Base58 encoding for Go

Base58 is a less known encoding, but it is popular when embedding resource identifiers into URLs.

The encoded data contains only alphanumericals, and avoids the easily confused characters 0, i, l and O (zero, india, lima, capital oscar).

The API docs for this package are online at http://godoc.org/github.com/tv42/base58

Documentation

Overview

Package base58 implements a human-friendly base58 encoding.

As opposed to base64 and friends, base58 is typically used to convert integers. You can use big.Int.SetBytes to convert arbitrary bytes to an integer first, and big.Int.Bytes the other way around.

Functions

func DecodeToBig

func DecodeToBig(src []byte) (*big.Int, error)

Decode a big integer from the bytes. Returns an error on corrupt input.

Example
n, err := DecodeToBig([]byte("CGy"))
if err != nil {
	fmt.Println("error:", err)
	return
}
fmt.Printf("%d\n", n)
Output:

123456

func EncodeBig

func EncodeBig(dst []byte, src *big.Int) []byte

Encode encodes src, appending to dst. Be sure to use the returned new value of dst.

Example
buf := EncodeBig(nil, big.NewInt(123456))
fmt.Printf("%s\n", buf)
Output:

CGy
