Constants

const PubKeyEd25519Size = 32

PubKeyEd25519Size is the number of bytes in an Ed25519 signature.

const (
	// Size of an Edwards25519 signature. Namely the size of a compressed
	// Edwards25519 point, and a field element. Both of which are 32 bytes.
	SignatureSize = 64
)

Functions

func IsPrivKeyEd25519ReprEmpty

func IsPrivKeyEd25519ReprEmpty(goor PrivKeyEd25519) (empty bool)

func IsPubKeyEd25519ReprEmpty

func IsPubKeyEd25519ReprEmpty(goor PubKeyEd25519) (empty bool)

Types

type PrivKeyEd25519

type PrivKeyEd25519 [64]byte

PrivKeyEd25519 implements crypto.PrivKey.

func GenPrivKey

func GenPrivKey() PrivKeyEd25519

GenPrivKey generates a new ed25519 private key. It uses OS randomness in conjunction with the current global random seed in tendermint/libs/common to generate the private key.

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 w/ type information.

func (PrivKeyEd25519) EmptyPBMessage

func (goo PrivKeyEd25519) EmptyPBMessage(cdc *amino.Codec) (msg proto.Message)

func (PrivKeyEd25519) Equals

func (privKey PrivKeyEd25519) Equals(other crypto.PrivKey) bool

Equals - you probably don't need to use this. Runs in constant time based on length of the keys.

func (*PrivKeyEd25519) FromPBMessage

func (goo *PrivKeyEd25519) FromPBMessage(cdc *amino.Codec, msg proto.Message) (err error)

func (PrivKeyEd25519) GetTypeURL

func (_ PrivKeyEd25519) GetTypeURL() (typeURL string)

func (PrivKeyEd25519) PubKey

func (privKey PrivKeyEd25519) PubKey() crypto.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. This assumes the privkey is wellformed in the golang format. The first 32 bytes should be random, corresponding to the normal ed25519 private key. The latter 32 bytes should be the compressed public key. If these conditions aren't met, Sign will panic or produce an incorrect signature.

func (PrivKeyEd25519) ToPBMessage

func (goo PrivKeyEd25519) ToPBMessage(cdc *amino.Codec) (msg proto.Message, err error)

type PubKeyEd25519

type PubKeyEd25519 [PubKeyEd25519Size]byte

PubKeyEd25519 implements crypto.PubKey for the Ed25519 signature scheme.

func (PubKeyEd25519) Address

func (pubKey PubKeyEd25519) Address() crypto.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) EmptyPBMessage

func (goo PubKeyEd25519) EmptyPBMessage(cdc *amino.Codec) (msg proto.Message)

func (PubKeyEd25519) Equals

func (pubKey PubKeyEd25519) Equals(other crypto.PubKey) bool

nolint: golint

func (*PubKeyEd25519) FromPBMessage

func (goo *PubKeyEd25519) FromPBMessage(cdc *amino.Codec, msg proto.Message) (err error)

func (PubKeyEd25519) GetTypeURL

func (_ PubKeyEd25519) GetTypeURL() (typeURL string)

func (PubKeyEd25519) String

func (pubKey PubKeyEd25519) String() string

func (PubKeyEd25519) ToPBMessage

func (goo PubKeyEd25519) ToPBMessage(cdc *amino.Codec) (msg proto.Message, err error)

func (PubKeyEd25519) VerifyBytes

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