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 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.
