Methods

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

pub fn from_bytes<B: AsRef<[u8]>>(bytes: B) -> Result<Self, Error>

Create an ECDSA public key from an elliptic curve point (compressed or uncompressed) encoded using the Elliptic-Curve-Point-to-Octet-String algorithm described in SEC 1: Elliptic Curve Cryptography (Version 2.0) section 2.3.3 (page 10).

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 Elliptic-Curve-Point-to-Octet-String algorithm described in SEC 1: Elliptic Curve Cryptography (Version 2.0) section 2.3.3 (page 10).

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 Elliptic-Curve-Point-to-Octet-String encoding i.e with the leading 0x04 byte in that encoding removed.
