Functions

func CurveTypes

func CurveTypes() map[CurveType]struct{}

CurveTypes returns all known curves

func Curves

func Curves() map[Curve]bool

Curves returns all curves we implement

Types

type Curve

type Curve uint16

Curve is used to represent the IANA registered curves for TLS

https://www.iana.org/assignments/tls-parameters/tls-parameters.xml#tls-parameters-8

const (
	P256   Curve = 0x0017
	P384   Curve = 0x0018
	X25519 Curve = 0x001d
)

Curve enums

func (Curve) String

func (c Curve) String() string

type CurvePointFormat

type CurvePointFormat byte

CurvePointFormat is used to represent the IANA registered curve points

https://www.iana.org/assignments/tls-parameters/tls-parameters.xml#tls-parameters-9

const (
	CurvePointFormatUncompressed CurvePointFormat = 0
)

CurvePointFormat enums

type CurveType

type CurveType byte

CurveType is used to represent the IANA registered curve types for TLS

https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-10

const (
	CurveTypeNamedCurve CurveType = 0x03
)

CurveType enums

type Keypair

type Keypair struct {
	Curve      Curve
	PublicKey  []byte
	PrivateKey []byte
}

Keypair is a Curve with a Private/Public Keypair

func GenerateKeypair

func GenerateKeypair(c Curve) (*Keypair, error)

GenerateKeypair generates a keypair for the given Curve
