Struct Signature

pub struct Signature { /* private fields */ }

A BBS+ signature.

Implementations

impl Signature

pub fn new( messages: &[SignatureMessage], signkey: &SecretKey, verkey: &PublicKey, ) -> Result<Self, BBSError>

No committed messages, All messages known to signer.

pub fn generate_blinding() -> SignatureBlinding

Generate the signature blinding factor that will be used to unblind the signature

pub fn verify( &self, messages: &[SignatureMessage], verkey: &PublicKey, ) -> Result<bool, BBSError>

Verify a signature. During proof of knowledge also, this method is used after extending the verkey

pub fn validate(&self) -> Result<(), BBSError>

Check if the signature is a valid form i.e. not infinity since it will always validate if that is the case

pub fn to_bytes_compressed_form(&self) -> [u8; 112]

Convert to raw bytes form

pub fn to_bytes_uncompressed_form(&self) -> [u8; 160]

Convert to raw bytes form

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl Default for Signature

fn default() -> Self

Returns the “default value” for a type.

impl<'a> Deserialize<'a> for Signature

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

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl From<&[u8; 112]> for Signature

fn from(data: &[u8; 112]) -> Self

Converts to this type from the input type.

impl From<&[u8; 160]> for Signature

fn from(data: &[u8; 160]) -> Self

Converts to this type from the input type.

impl From<[u8; 112]> for Signature

fn from(data: [u8; 112]) -> Self

Converts to this type from the input type.

impl From<[u8; 160]> for Signature

fn from(data: [u8; 160]) -> Self

Converts to this type from the input type.

impl From<Box<[u8]>> for Signature

fn from(data: Box<[u8]>) -> Signature

Converts to this type from the input type.

impl Into<Box<[u8]>> for Signature

fn into(self) -> Box<[u8]>

Converts this type into the (usually inferred) input type.

impl PartialEq for Signature

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for Signature

type Error = BBSError

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<u8>> for Signature

type Error = BBSError

The type returned in the event of a conversion error.

fn try_from(value: Vec<u8>) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Signature
