Enum HhppSignatureScheme 

pub enum HhppSignatureScheme {
    Ed25519,
    HybridInterim,
    HybridStandard,
}

Which signature scheme the hub expects on its HashedHubPseudonymPackage (HHPP), and thus which key PHC signs it with.

Hubs predating the hybrid post-quantum migration verify a classical ed25519 (EdDSA) signature against the constellation’s phc_jwt_key; newer hubs verify the hybrid composite signature against phc_verifying_key. The hub advertises its choice via hub::EnterStartResp, the global client relays it to phc::user::HhppEP, and PHC signs accordingly.

Absent on the wire ⇒ Ed25519, so hubs and global clients predating this field keep getting a signature they can verify. Each variant’s wire value is the JWS alg the HHPP will carry.

Variants

Ed25519

Classical ed25519 (EdDSA), verifiable by pre-hybrid hubs. The default.

HybridInterim

PubHubs’ interim, non-conformant hybrid composite (empty ML-DSA context) — the only hybrid PHC currently signs with. Its wire value matches crate::common::dsa::ALG.

HybridStandard

The conformant LAMPS-standard composite. Not yet implemented: PHC rejects requests for it until aws_lc_rs exposes an ML-DSA context (see crate::common::dsa). Reserved here so the wire protocol already carries its identifier.

Implementations

impl HhppSignatureScheme

pub fn is_default(&self) -> bool

true for the default (Ed25519). Used with skip_serializing_if to omit the field from the wire when it is the default, so peers predating it — which deny_unknown_fields — still accept the message (e.g. a PHC that hasn’t learned the field).

Trait Implementations

impl Clone for HhppSignatureScheme

fn clone(&self) -> HhppSignatureScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HhppSignatureScheme

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

Formats the value using the given formatter.

impl Default for HhppSignatureScheme

fn default() -> HhppSignatureScheme

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HhppSignatureScheme

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HhppSignatureScheme

fn eq(&self, other: &HhppSignatureScheme) -> 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 Serialize for HhppSignatureScheme

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for HhppSignatureScheme
