Documentation

Overview

The crypto package is used to provide functionality to several keypair types. The current supported types are secp256k1 and sr25519.

Keypairs

The keypair interface is used to bridge the different types of crypto formats. Every Keypair has both a Encode and Decode function that allows writing and reading from keystore files. There is also the Address and PublicKey functions that allow access to public facing fields.

Types

Functions

func ConvertAndEncode

func ConvertAndEncode(hrp string, data []byte) (string, error)

ConvertAndEncode converts from a base64 encoded byte string to base32 encoded byte string and then to bech32.

func DecodeAndConvert

func DecodeAndConvert(bech string) (string, []byte, error)

DecodeAndConvert decodes a bech32 encoded string and converts to base64 encoded bytes.
