func DecompressPubkey

func DecompressPubkey(pubkey []byte) (*ecdsa.PublicKey, error)

DecompressPubkey parses a public key in the 33-byte compressed format.

func Ecrecover

func Ecrecover(digestHash, sig []byte) (ecc.PublicKey, error)

Ecrecover returns the uncompressed public key that created the given signature.

func FromECDSAPub
