Variants

Ed25519

Plain Ed25519.

Ed25519Nkey

Ed25519 used as a NATS NKey.

Rs256

JWS RS256.

Es256

JWS ES256.

MlDsa44

ML-DSA parameter level 44.

MlDsa65

ML-DSA parameter level 65.

MlDsa87

ML-DSA parameter level 87.

Implementations

impl SignatureAlgorithm

pub const fn is_ml_dsa(self) -> bool

Whether this is a post-quantum ML-DSA signing algorithm (the family routed through the local-software crypto provider).

pub const fn token(self) -> &'static str

The stable kebab-case token for this algorithm (used in audit + diagnostics).

pub const fn native_algorithm(self) -> Option<NativeAlgorithm>

The backend-native NativeAlgorithm this signing algorithm maps to, for the capability probe (Backend::supports_native_algorithm). Some only for the ML-DSA family: classical signing algorithms always custody in place and never consult the PQC native probe.

Trait Implementations

impl Clone for SignatureAlgorithm

fn clone(&self) -> SignatureAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SignatureAlgorithm

impl Debug for SignatureAlgorithm

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

Formats the value using the given formatter.

impl Eq for SignatureAlgorithm

impl PartialEq for SignatureAlgorithm

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