Enum SignatureScheme 

#[repr(u8)]
pub enum SignatureScheme {
    Ed25519 = 1,
    Dilithium = 2,
    Falcon = 3,
    Sphincs = 4,
    HybridEd25519Dilithium = 5,
}

Signature scheme identifier. First byte of every encoded Signature / PubKey.

Versioned from day one so a post-quantum migration is a protocol upgrade, not a wire-format rewrite. See docs/SECURITY.md §12.

Variants

Ed25519 = 1

Ed25519 (EdDSA over Curve25519). Genesis default.

Dilithium = 2

Reserved for ML-DSA / Dilithium (NIST FIPS 204). Post-quantum.

Falcon = 3

Reserved for Falcon (NIST FIPS 205 draft). Post-quantum, smaller sigs than Dilithium.

Sphincs = 4

Reserved for SLH-DSA / SPHINCS+ (NIST FIPS 205). Hash-based, stateless.

HybridEd25519Dilithium = 5

Reserved for hybrid Ed25519 + Dilithium (belt-and-braces during migration).

Implementations

impl SignatureScheme

pub const fn is_active(&self) -> bool

Schemes currently implemented and accepted by consensus.

pub const fn pubkey_len(&self) -> usize

Expected public-key length in bytes for this scheme.

pub const fn signature_len(&self) -> usize

Expected signature length in bytes for this scheme.

Trait Implementations

impl BorshDeserialize for SignatureScheme

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for SignatureScheme

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for SignatureScheme

fn clone(&self) -> SignatureScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureScheme

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SignatureScheme

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl EnumExt for SignatureScheme

fn deserialize_variant<__R: Read>( reader: &mut __R, variant_tag: u8, ) -> Result<Self, Error>

Deserialises given variant of an enum from the reader.

impl Hash for SignatureScheme

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 SignatureScheme

fn eq(&self, other: &SignatureScheme) -> 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 SignatureScheme

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 SignatureScheme

impl Eq for SignatureScheme

impl StructuralPartialEq for SignatureScheme
