}

ECDSA public keys

Variants

Compressed(CompressedCurvePoint<C>)

Compressed Weierstrass elliptic curve point

Uncompressed(UncompressedCurvePoint<C>)

Uncompressed Weierstrass elliptic curve point

Methods

impl<C> PublicKey<C> where     C: WeierstrassCurve,

pub fn from_slice(slice: &[u8]) -> Result<Self, Error>

Create an ECDSA public key from an elliptic curve point (compressed or uncompressed) encoded using the Octet-String-to-Elliptic-Curve-Point algorithm described in SEC 1: Elliptic Curve Cryptography (Version 2.0) section 2.3.4 (page 11).

pub fn from_compressed_point<B>(into_bytes: B) -> Result<Self, Error> where     B: Into<GenericArray<u8, C::CompressedPointSize>>,

Create an ECDSA public key from an compressed elliptic curve point encoded using the Octet-String-to-Elliptic-Curve-Point algorithm described in SEC 1: Elliptic Curve Cryptography (Version 2.0) section 2.3.4 (page 11).

pub fn from_untagged_point(     bytes: &GenericArray<u8, C::UntaggedPointSize> ) -> Self

Create an ECDSA public key from a raw uncompressed point serialized as a bytestring, without a 0x04-byte tag.

This will be twice the modulus size, or 1-byte smaller than the Octet-String-to-Elliptic-Curve-Point encoding i.e with the leading 0x04 byte in that encoding removed.
