Functions

func AlgorithmForCurve

func AlgorithmForCurve(crv elliptic.Curve) (jwa.EllipticCurveAlgorithm, bool)

func AllocECPointBuffer

func AllocECPointBuffer(v *big.Int, crv elliptic.Curve) []byte

AllocECPointBuffer allocates a buffer for the given point in the given curve. This buffer should be released using the ReleaseECPointBuffer function.

func AvailableAlgorithms

func AvailableAlgorithms() []jwa.EllipticCurveAlgorithm

func AvailableCurves

func AvailableCurves() []elliptic.Curve

func CalculateKeySize

func CalculateKeySize(crv elliptic.Curve) int

func CurveForAlgorithm

func CurveForAlgorithm(alg jwa.EllipticCurveAlgorithm) (elliptic.Curve, bool)

func IsAvailable

func IsAvailable(alg jwa.EllipticCurveAlgorithm) bool

func RegisterCurve

func RegisterCurve(crv elliptic.Curve, alg jwa.EllipticCurveAlgorithm)

func ReleaseECPointBuffer

func ReleaseECPointBuffer(buf []byte)

ReleaseECPointBuffer releases the []byte buffer allocated.
