Struct solana_libra_nextgen_crypto::ed25519::Ed25519Signature

pub struct Ed25519Signature(_);

An Ed25519 signature

Methods

impl Ed25519Signature

pub fn to_bytes(&self) -> [u8; 64]

Serialize an Ed25519Signature.

pub fn check_malleability(bytes: &[u8]) -> Result<(), CryptoMaterialError>

Check for correct size and malleability issues. This method ensures s is of canonical form and R does not lie on a small group.

Trait Implementations

impl Signature for Ed25519Signature

type VerifyingKeyMaterial = Ed25519PublicKey

The associated verifying key type for this signature.

type SigningKeyMaterial = Ed25519PrivateKey

The associated signing key type for this signature

fn verify(
    &self,
    message: &HashValue,
    public_key: &Ed25519PublicKey
) -> Result<()>

Checks that self is valid for message using public_key.

fn verify_arbitrary_msg(
    &self,
    message: &[u8],
    public_key: &Ed25519PublicKey
) -> Result<()>

Checks that self is valid for an arbitrary &u8 message using public_key. Outside of this crate, this particular function should only be used for native signature verification in move

fn batch_verify_signatures(
    message: &HashValue,
    keys_and_signatures: Vec<(Self::VerifyingKeyMaterial, Self)>
) -> Result<()>

Batch signature verification as described in the original EdDSA article by Bernstein et al. "High-speed high-security signatures". Current implementation works for signatures on the same message and it checks for malleability.

fn to_bytes(&self) -> Vec<u8>

Convert the signature into a byte representation.

impl Clone for Ed25519Signature

fn clone(&self) -> Ed25519Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<Ed25519Signature> for LegacySignature

fn from(signature: Ed25519Signature) -> Self

Performs the conversion.

impl From<Signature> for Ed25519Signature

fn from(sig: LegacySignature) -> Self

Performs the conversion.

impl PartialEq<Ed25519Signature> for Ed25519Signature

fn eq(&self, other: &Ed25519Signature) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Eq for Ed25519Signature

impl Debug for Ed25519Signature

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

Formats the value using the given formatter.

impl Hash for Ed25519Signature

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, 

Feeds a slice of this type into the given [Hasher].

impl<'_> TryFrom<&'_ [u8]> for Ed25519Signature

type Error = CryptoMaterialError

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Ed25519Signature, CryptoMaterialError>

Performs the conversion.

impl Serialize for Ed25519Signature

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for Ed25519Signature

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
