Struct Signature 

pub struct Signature(pub(crate) Signature);

A secp256k1 ECDSA signature over SHA-256, in 64-byte compact r || s form.

Every value of this type that this crate produces is low-S; see the module docs.

Implementations

impl Signature

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

The 64-byte compact r || s encoding, which is what atproto puts in a record’s sig field.

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

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

This accepts a high-S signature — rejecting malleability is VerifyingKey::verify’s job, so that a signature from elsewhere can be parsed and then be honestly reported as failing to verify.

pub fn is_low_s(&self) -> bool

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

pub fn as_k256(&self) -> &Signature

The underlying k256 signature, for callers that need r, s, or DER.

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 From<Signature<Secp256k1>> for Signature

fn from(inner: Signature) -> Self

Converts to this type from the input type.

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.
