Functions ¶

func DeterministicNewPrivateKey ¶

func DeterministicNewPrivateKey(curve elliptic.Curve, rand io.Reader) (*btcSecp256k1.PrivateKey, error)

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 Join ¶

func Join(s [][]byte) []byte

Join() is faster than bytes.Join because it does what bytes.Join() does without appending (empty) separators

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
	ConsKey cryptotypes.PrivKey
	// 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

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)
