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.

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) 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.

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) Equals

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

nolint: golint

func (PubKeyEd25519) String

func (pubKey PubKeyEd25519) String() string

func (PubKeyEd25519) VerifyBytes

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