Struct Signature

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

ECDSA signature object.

Implementations

impl Signature

pub fn to_be_bytes(&self) -> Box<[u8]>

Returns the signature serialized as concatenated r and s in big endian order (32+32 bytes).

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

Restores the signature from concatenated r and s in big endian order (32+32 bytes).

pub fn to_der_bytes(&self) -> Box<[u8]>

Returns the signature serialized in ASN.1 DER format.

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

Restores the signature from a bytestring in ASN.1 DER format.

pub fn verify(&self, verifying_pk: &PublicKey, message: &[u8]) -> bool

Verifies that the given message was signed with the secret counterpart of the given key. The message is hashed internally.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate 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<'de> Deserialize<'de> for Signature

Available on crate feature serde only.

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

where D: Deserializer<'de>,

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 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

Available on crate feature serde only.

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFromBytes for Signature

Available on crate feature serde only.

type Error = String

The error returned on construction failure.

fn try_from_bytes(bytes: &[u8]) -> Result<Self, Self::Error>

Attempts to construct an object from a byte slice.

impl Eq for Signature

impl StructuralPartialEq for Signature
