Struct Signature 

pub struct Signature(Signature);

A P-256 ECDSA signature over SHA-256, in 64-byte compact r || s form.

Tuple Fields

0: Signature

Implementations

impl Signature

pub fn from_bytes(bytes: &[u8; 64]) -> Result<Self, KeyError>

Parses a 64-byte compact r || s signature.

A high-s signature parses. Refusing malleability is VerifyingKey::verify’s job, so that a signature from elsewhere can be read and then honestly reported as one atproto does not accept.

pub fn to_bytes(&self) -> [u8; 64]

The 64-byte compact r || s encoding.

pub fn is_low_s(&self) -> bool

Whether s is in the lower half of the curve order, as atproto requires.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl PartialEq for Signature

fn eq(&self, other: &Signature) -> 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.

impl Copy for Signature

impl Eq for Signature

impl StructuralPartialEq for Signature
