func PubKeyFromBytes64 ¶ added in v0.1.2

func PubKeyFromBytes64(pubkey []byte) (*stdecdsa.PublicKey, error)

PubKeyFromBytes64 returns the public key from the 64 byte uncompressed version. It adds the prefix (0x04 for uncompressed keys) to the input bytes.

func PubKeyPBToAddress ¶

func PubKeyPBToAddress(pubkey cryptopb.PublicKey) (common.Address, error)

PubKeyPBToAddress returns the Ethereum address for the given k1 public key.

func PubKeyToAddress ¶

func PubKeyToAddress(pubkey crypto.PubKey) (common.Address, error)

PubKeyToAddress returns the Ethereum address for the given k1 public key.

func PubKeyToBytes64 ¶ added in v0.1.2

func PubKeyToBytes64(pubkey *stdecdsa.PublicKey) []byte

PubKeyToBytes64 returns the 64 byte uncompressed version of the public key, by removing the prefix (0x04 for uncompressed keys).

func PubKeyToCosmos ¶

func PubKeyToCosmos(pubkey crypto.PubKey) (cosmoscrypto.PubKey, error)

func Sign ¶

func Sign(key crypto.PrivKey, input [32]byte) ([65]byte, error)

Sign returns a signature from input data.

The produced signature is 65 bytes in the [R || S || V] format where V is 27 or 28.

func StdPrivKeyFromComet ¶ added in v0.1.2

func StdPrivKeyFromComet(privkey crypto.PrivKey) (*stdecdsa.PrivateKey, error)

func StdPubKeyToCosmos ¶ added in v0.1.2

func StdPubKeyToCosmos(pubkey *stdecdsa.PublicKey) (cosmoscrypto.PubKey, error)

func Verify ¶

func Verify(address common.Address, hash [32]byte, sig [65]byte) (bool, error)

Verify returns whether the 65 byte signature is valid for the provided hash and Ethereum address.

Note the signature MUST be 65 bytes in the Ethereum [R || S || V] format.
