Enum AnySigningKey 

pub enum AnySigningKey {
    K256(SigningKey),
    P256(SigningKey),
}

A private signing key that may be one of several supported curves.

Mirrors AnyVerifyingKey for the signing side. Signatures produced by sign are always low-s normalized to match the atproto convention already established by AnySignature.

Variants

K256(SigningKey)

secp256k1 signing key.

P256(SigningKey)

P-256 signing key.

Implementations

impl AnySigningKey

pub fn verifying_key(&self) -> AnyVerifyingKey

Returns the corresponding verifying key.

pub fn jwt_alg(&self) -> &'static str

Returns the JWT alg header identifier for this key’s curve (“ES256K” for secp256k1, “ES256” for P-256).

pub fn sign(&self, msg: &[u8]) -> AnySignature

Signs the SHA-256 prehash of msg and returns the signature in low-s normalized form.

The returned AnySignature is guaranteed to satisfy AnyVerifyingKey::verify_prehash against the corresponding verifying key when given the same prehash bytes.

pub fn sign_prehash(&self, prehash: &[u8; 32]) -> AnySignature

Signs a precomputed 32-byte SHA-256 prehash directly.

Trait Implementations

impl Clone for AnySigningKey

fn clone(&self) -> AnySigningKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnySigningKey

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

Formats the value using the given formatter.
