Implementations

impl Secp256r1PublicKey

pub fn new(gx: [u8; 32], gy: [u8; 32]) -> Option<Self>

Constructs a new Secp256r1PublicKey from the given x and y coordinates.

This function attempts to create a public key from uncompressed x and y coordinates. It returns None if the provided coordinates do not correspond to a valid point on the curve.

• Parameters:

  • gx: The x coordinate of the public key.
  • gy: The y coordinate of the public key.

• Returns: An Option<Secp256r1PublicKey>.

pub fn from_public_key(public_key: PublicKey) -> Self

Constructs a Secp256r1PublicKey from an existing PublicKey.

This method can be used to convert a PublicKey from the p256 crate into a Secp256r1PublicKey.

• Parameter public_key: A PublicKey instance.

• Returns: A Secp256r1PublicKey instance.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, CryptoError>

Constructs a Secp256r1PublicKey from a byte slice.

Attempts to parse a byte slice as an encoded elliptic curve point and create a public key. Returns a CryptoError if the byte slice does not represent a valid public key.

• Parameter bytes: A byte slice representing an encoded elliptic curve point.

• Returns: A Result<Secp256r1PublicKey, CryptoError>.

pub fn verify( &self, message: &[u8], signature: &Secp256r1Signature, ) -> Result<(), CryptoError>

Verifies a digital signature against a message using this public key.

This method checks if the provided signature is valid for the given message under this public key. Returns a CryptoError if the signature verification fails.

• Parameters:

  • message: The message that was signed.
  • signature: The signature to verify.

• Returns: A Result<(), CryptoError>.

pub fn get_encoded(&self, compressed: bool) -> Vec<u8>

Gets this public key’s elliptic curve point encoded as defined in section 2.3.3 of SEC1.

• Parameter compressed: If the EC point should be encoded in compressed or uncompressed format

• Returns: The encoded public key

pub fn get_encoded_point(&self, compressed: bool) -> EncodedPoint

pub fn get_encoded_compressed_hex(&self) -> String

Gets this public key’s elliptic curve point encoded as defined in section 2.3.3 of SEC1 in compressed format as hexadecimal.

• Returns: The encoded public key in compressed format as hexadecimal without a prefix

pub fn from_encoded(encoded: &str) -> Option<Self>

Constructs a Secp256r1PublicKey from a hexadecimal string representation.

This method attempts to parse a hexadecimal string as an encoded elliptic curve point. Returns None if the string is not a valid encoding or does not represent a valid public key.

• Parameter encoded: A hexadecimal string representing an encoded elliptic curve point.

• Returns: An Option<Secp256r1PublicKey>.
