Actions Status

import "github.com/eknkc/basex"

Package basex provides fast base encoding / decoding of any given alphabet using bitcoin style leading zero compression. It is a GO port of https://github.com/cryptocoinjs/base-x

Usage

type Encoding

type Encoding struct {
}

Encoding is a custom base encoding defined by an alphabet. It should bre created using NewEncoding function

func NewEncoding

func NewEncoding(alphabet string) (*Encoding, error)

NewEncoding returns a custom base encoder defined by the alphabet string. The alphabet should contain non-repeating characters. Ordering is important. Example alphabets:

- base2: 01
- base16: 0123456789abcdef
- base32: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
- base62: 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

func (*Encoding) Decode

func (e *Encoding) Decode(source string) ([]byte, error)

Decode function decodes a string previously obtained from Encode, using the same alphabet and returns a byte slice In case the input is not valid an arror will be returned

func (*Encoding) Encode

func (e *Encoding) Encode(source []byte) string
