Overview

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

It has been copied from github.com/eknkc/basex to avoid that external dependency, and updated somewhat for efficiency.

Types

type Encoding

type Encoding struct {
	// contains filtered or unexported fields
}

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. It does not allow non-ASCII characters in the alphabet. 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

Encode function receives a byte slice and encodes it to a string using the alphabet provided
