Functions

func EncodeUint64

func EncodeUint64(val uint64) []byte

EncodeUint64 encodes a uint64 value to a byte array

func ExtractSignerAddress

func ExtractSignerAddress(data Signable) (sdk.AccAddress, error)

ExtractSignerAddress extracts the signer address of data

func GenerateFloatingKey

func GenerateFloatingKey() (secretKey *btcSecp256k1.PrivateKey, addr sdk.AccAddress)

GenerateFloatingKey creates a new private key with an account address derived from the corresponding public key

func GetKeyName

func GetKeyName(clientCtx client.Context) (string, error)

func GetPrivKey

func GetPrivKey(clientCtx client.Context, keyName string) (*btcSecp256k1.PrivateKey, error)

func HashMsg

func HashMsg(msgData []byte) []byte

HashMsg hashes msgData using SHA-256

func RecoverPubKey

func RecoverPubKey(data Signable) (secp256k1.PubKey, error)

RecoverPubKey recovers the public key from data's signature

func Sign

func Sign(pkey *btcSecp256k1.PrivateKey, data Signable) ([]byte, error)

Sign creates a signature for a struct. The prepareFunc prepares the struct before extracting the data for the signature

Types

type Account

type Account struct {
	SK      *btcSecp256k1.PrivateKey
	PubKey  cryptotypes.PubKey
	Addr    sdk.AccAddress

	Vault   *Account // provider vault account (only for provider)
	// contains filtered or unexported fields
}

func GenerateDeterministicFloatingKey

func GenerateDeterministicFloatingKey(rand io.Reader) (acc Account)

GenerateDeterministicFloatingKey creates a new private key with an account address derived from the corresponding public key using a rand source

func (Account) GetVaultAddr

func (acc Account) GetVaultAddr() string

type Signable

type Signable interface {
	// GetSignature gets the object's signature
	GetSignature() []byte
	// DataToSign processes the object's data before it's hashed and signed
	DataToSign() []byte
	// HashRounds gets the number of times the object's data is hashed before it's signed
	HashRounds() int
}

type ZeroReader

type ZeroReader struct {
	Seed byte
	// contains filtered or unexported fields
}

func NewZeroReader

func NewZeroReader(seed int64) *ZeroReader

func (*ZeroReader) Inc

func (z *ZeroReader) Inc()

func (ZeroReader) Read

func (z ZeroReader) Read(p []byte) (n int, err error)
