Enum SignatureAlgorithm 

#[non_exhaustive]
pub enum SignatureAlgorithm {
    EcdsaP256,
    EcdsaP384,
    RsaPss2048,
    Ed25519,
}

Signatur-Algorithmus fuer Delegation-Links.

Default-Empfehlung: SignatureAlgorithm::EcdsaP256 — kompakte Signatur (~64 byte), schnelle Verify auf Edge-Hardware.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EcdsaP256

ECDSA mit P-256 + SHA-256, fixed-length encoding (64 byte sig).

EcdsaP384

ECDSA mit P-384 + SHA-384, fixed-length encoding (96 byte sig).

RsaPss2048

RSA-PSS mit 2048-bit Key + SHA-256 (256 byte sig).

Ed25519

Ed25519 (64 byte sig).

Implementations

impl SignatureAlgorithm

pub const fn wire_id(self) -> u8

Wire-Id fuer das deterministische Sign-Input-Layout.

pub const fn from_wire_id(id: u8) -> Option<Self>

Decode aus Wire-Id; None bei unknown-Algorithm.

pub const fn expected_signature_len(self) -> Option<usize>

Erwartete Signatur-Laenge in Bytes (fixed) oder None fuer variabel (RSA-PSS abhaengig von Key-Size — wir fixieren auf 2048 und damit 256 byte).

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 Debug for SignatureAlgorithm

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

Formats the value using the given formatter.

impl Hash for SignatureAlgorithm

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
