Struct EcdsaSigRef

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

A reference to an EcdsaSig.

Implementations

impl EcdsaSigRef

pub fn to_der(&self) -> Result<Vec<u8>, ErrorStack>

Serializes the ECDSA signature into a DER-encoded ECDSASignature structure.

This corresponds to i2d_ECDSA_SIG.

pub fn verify<T>( &self, data: &[u8], eckey: &EcKeyRef<T>, ) -> Result<bool, ErrorStack>

where T: HasPublic,

Verifies if the signature is a valid ECDSA signature using the given public key.

This corresponds to ECDSA_do_verify.

pub fn r(&self) -> &BigNumRef

Returns internal component: r of an EcdsaSig. (See X9.62 or FIPS 186-2)

This corresponds to ECDSA_SIG_get0.

pub fn s(&self) -> &BigNumRef

Returns internal components: s of an EcdsaSig. (See X9.62 or FIPS 186-2)

This corresponds to ECDSA_SIG_get0.

Trait Implementations

impl AsRef<EcdsaSigRef> for EcdsaSig

fn as_ref(&self) -> &EcdsaSigRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<EcdsaSigRef> for EcdsaSig

fn borrow(&self) -> &EcdsaSigRef

Immutably borrows from an owned value.

impl ForeignTypeRef for EcdsaSigRef

type CType = ECDSA_SIG

The raw C type.

unsafe fn from_ptr<'a>(ptr: *mut Self::CType) -> &'a Self

Constructs a shared instance of this type from its raw type.

unsafe fn from_ptr_mut<'a>(ptr: *mut Self::CType) -> &'a mut Self

Constructs a mutable reference of this type from its raw type.

fn as_ptr(&self) -> *mut Self::CType

Returns a raw pointer to the wrapped value.
