Functions

func VerifySignature

func VerifySignature(data []byte, signature Signature, publicKey *ecdsa.PublicKey) bool

VerifySignature verifies a signature made over data with the corresponding public key

Types

type Signature

type Signature struct {
	R, S *big.Int
}

Signature representates the signature pair (r,s)

func CreateSignature

func CreateSignature(data []byte, privateKey *ecdsa.PrivateKey) (Signature, error)

CreateSignature creates a signature over data with the provided private Key.

func ParseSignature

func ParseSignature(signatureBase64 string) (Signature, error)

ParseSignature parses base64 encoded signature: base64(r|s)

func (Signature) Serialize

func (s Signature) Serialize() string

Serialize serializes the signature pair(r,s) => base64(r|s)
