Functions ¶

func MakePublicKey ¶

func MakePublicKey(privateKey *[64]byte) (publicKey *[32]byte)

MakePublicKey makes a publicKey from the first half of privateKey.

func Sha256 ¶

func Sha256(bytes []byte) []byte

func Sign ¶

func Sign(privateKey *[PrivateKeySize]byte, message []byte) *[SignatureSize]byte

Sign signs the message with privateKey and returns a signature.

func Sum ¶

func Sum(bz []byte) []byte

Sum returns the first 20 bytes of SHA256 of the bz.

func Verify ¶

func Verify(publicKey *[PublicKeySize]byte, message []byte, sig *[SignatureSize]byte) bool

Verify returns true iff sig is a valid signature of message by publicKey.

Types ¶

type Address ¶

type Address = HexBytes

type HexBytes ¶

type HexBytes []byte

func (HexBytes) Bytes ¶

func (bz HexBytes) Bytes() []byte

type PrivKey ¶

type PrivKey interface {
	Bytes() []byte
	Sign(msg []byte) ([]byte, error)
	PubKey() PubKey
}

type PrivKeyEd25519 ¶

type PrivKeyEd25519 [64]byte

PrivKeyEd25519 implements crypto.PrivKey.

func GenPrivKeyFromSecret ¶

func GenPrivKeyFromSecret(secret []byte) PrivKeyEd25519

GenPrivKeyFromSecret hashes the secret with SHA2, and uses that 32 byte output to create the private key. NOTE: secret should be the output of a KDF like bcrypt, if it's derived from user input.

func (PrivKeyEd25519) Bytes ¶

func (privKey PrivKeyEd25519) Bytes() []byte

Bytes marshals the privkey using amino encoding.

func (PrivKeyEd25519) PubKey ¶

func (privKey PrivKeyEd25519) PubKey() PubKey

PubKey gets the corresponding public key from the private key.

func (PrivKeyEd25519) Sign ¶

func (privKey PrivKeyEd25519) Sign(msg []byte) ([]byte, error)

Sign produces a signature on the provided message.

type PubKey ¶

type PubKey interface {
	Address() Address
	Bytes() []byte
	VerifyBytes(msg []byte, sig []byte) bool
}

type PubKeyEd25519 ¶

type PubKeyEd25519 [32]byte

PubKeyEd25519 implements crypto.PubKey for the Ed25519 signature scheme.

func (PubKeyEd25519) Address ¶

func (pubKey PubKeyEd25519) Address() Address

Address is the SHA256-20 of the raw pubkey bytes.

func (PubKeyEd25519) Bytes ¶

func (pubKey PubKeyEd25519) Bytes() []byte

Bytes marshals the PubKey using amino encoding.

func (PubKeyEd25519) VerifyBytes ¶

func (pubKey PubKeyEd25519) VerifyBytes(msg []byte, sig_ []byte) bool
