Functions

func NewBatchVerifier

func NewBatchVerifier() crypto.BatchVerifier

Types

type BatchVerifier

type BatchVerifier struct {
	*sr25519.BatchVerifier
}

BatchVerifier implements batch verification for sr25519.

func (*BatchVerifier) Add

func (b *BatchVerifier) Add(key crypto.PubKey, msg, signature []byte) error

func (*BatchVerifier) Verify

func (b *BatchVerifier) Verify() (bool, []bool)

type PrivKey

type PrivKey struct {
	// contains filtered or unexported fields
}

PrivKey implements crypto.PrivKey.

func GenPrivKey

func GenPrivKey() PrivKey

GenPrivKey generates a new sr25519 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) PrivKey

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 (PrivKey) Bytes

func (privKey PrivKey) Bytes() []byte

Bytes returns the byte-encoded PrivKey.

func (PrivKey) Equals

func (privKey PrivKey) 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 (PrivKey) MarshalJSON

func (privKey PrivKey) MarshalJSON() ([]byte, error)

func (PrivKey) PubKey

func (privKey PrivKey) PubKey() crypto.PubKey

PubKey gets the corresponding public key from the private key.

Panics if the private key is not initialized.

func (PrivKey) Sign

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

Sign produces a signature on the provided message.

func (PrivKey) Type

func (privKey PrivKey) Type() string

func (PrivKey) TypeTag

func (PrivKey) TypeTag() string

TypeTag satisfies the jsontypes.Tagged interface.

func (*PrivKey) UnmarshalJSON

func (privKey *PrivKey) UnmarshalJSON(data []byte) error

type PubKey

type PubKey []byte

PubKey implements crypto.PubKey.

func (PubKey) Address

func (pubKey PubKey) Address() crypto.Address

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

func (PubKey) Bytes

func (pubKey PubKey) Bytes() []byte

Bytes returns the PubKey byte format.

func (PubKey) Equals

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

func (PubKey) String

func (pubKey PubKey) String() string

func (PubKey) Type

func (pubKey PubKey) Type() string

func (PubKey) TypeTag

func (PubKey) TypeTag() string

TypeTag satisfies the jsontypes.Tagged interface.

func (PubKey) VerifySignature

func (pubKey PubKey) VerifySignature(msg []byte, sigBytes []byte) bool
