Trait yubihsm::ecdsa::sec1::FromEncodedPoint

pub trait FromEncodedPoint<C>: Sizedwhere
    C: Curve,
    <C as Curve>::FieldBytesSize: ModulusSize,{
    // Required method
    fn from_encoded_point(
        point: &EncodedPoint<<C as Curve>::FieldBytesSize>
    ) -> CtOption<Self>;
}

Available on crate feature sec1 only.

Trait for deserializing a value from a SEC1 encoded curve point.

This is intended for use with the AffinePoint type for a given elliptic curve.

Required Methods

fn from_encoded_point( point: &EncodedPoint<<C as Curve>::FieldBytesSize> ) -> CtOption<Self>

Deserialize the type this trait is impl’d on from an EncodedPoint.
