Struct VerificationKey

pub struct VerificationKey(/* private fields */);

MultiSig verification key, which is a wrapper over the BlstVk (element in G2) from the blst library.

Implementations

impl VerificationKey

pub fn to_bytes(self) -> [u8; 96]

Convert an VerificationKey to its compressed byte representation.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, MultiSignatureError>

Convert a compressed byte string into a VerificationKey.

Error

This function fails if the bytes do not represent a compressed point of the prime order subgroup of the curve Bls12-381.

Trait Implementations

impl Clone for VerificationKey

fn clone(&self) -> VerificationKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VerificationKey

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

Formats the value using the given formatter.

impl Default for VerificationKey

fn default() -> VerificationKey

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VerificationKey

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for VerificationKey

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

Formats the value using the given formatter.

impl From<&SigningKey> for VerificationKey

fn from(sk: &SigningKey) -> Self

Convert a secret key into an MspMvk. This is performed by computing MspMvk = g2 * sk, where g2 is the generator in G2. We can use the blst built-in function sk_to_pk.

impl Hash for VerificationKey

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 Ord for VerificationKey

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for VerificationKey

fn eq(&self, other: &Self) -> 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 PartialOrd for VerificationKey

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for VerificationKey

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> Sum<&'a VerificationKey> for VerificationKey

fn sum<I>(iter: I) -> Self

where I: Iterator<Item = &'a Self>,

Takes an iterator and generates Self from the elements by “summing up” the items.

impl Copy for VerificationKey
