pub struct PublicKey<C: IntrinsicCurve> { /* private fields */ }

Implementations§

Source§

impl<C: IntrinsicCurve> PublicKey<C>
where C::Point: WeierstrassPoint + Group + FromCompressed<<<C as IntrinsicCurve>::Point as WeierstrassPoint>::Coordinate>, <<C as IntrinsicCurve>::Point as WeierstrassPoint>::Coordinate: IntMod,

Source

pub fn from_affine(point: <C as IntrinsicCurve>::Point) -> Result<Self>

Convert an AffinePoint into a PublicKey. In addition, for Coordinate<C> implementing IntMod, this function will assert that the affine coordinates of point are both in canonical form.

This does not check that point is on the curve. Use this only with points that have already been checked. For public keys from untrusted bytes, use Self::from_sec1_bytes.

Source

pub fn from_sec1_bytes(bytes: &[u8]) -> Result<Self>
where for<'a> &'a <<C as IntrinsicCurve>::Point as WeierstrassPoint>::Coordinate: Mul<&'a <<C as IntrinsicCurve>::Point as WeierstrassPoint>::Coordinate, Output = <<C as IntrinsicCurve>::Point as WeierstrassPoint>::Coordinate>,

§Safety
  • The uncompressed deserialization checks that the point is on the curve but does not perform any additional subgroup checks.
