Struct EcdsaSignature 

pub struct EcdsaSignature { /* private fields */ }

Raw ECDSA signature pair (r, s).

Both components are positive integers in [1, n) relative to the subgroup order of the signing curve. The serialized form is a DER SEQUENCE of two INTEGER values, matching the shape used by DsaSignature.

Implementations

impl EcdsaSignature

pub fn r(&self) -> &BigUint

pub fn s(&self) -> &BigUint

pub fn to_key_blob(&self) -> Vec<u8>

Encode the signature as a DER SEQUENCE of (r, s).

pub fn from_key_blob(blob: &[u8]) -> Option<Self>

Decode a crate-defined binary ECDSA signature.

Zero values are rejected immediately. Range checks against the curve order happen during verification because the signature encoding does not carry the curve parameters.

Trait Implementations

impl Clone for EcdsaSignature

fn clone(&self) -> EcdsaSignature

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EcdsaSignature

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EcdsaSignature

fn eq(&self, other: &EcdsaSignature) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
