Struct EcdsaSig 

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

A low level interface to ECDSA.

Implementations

impl EcdsaSig

pub fn sign<T>(data: &[u8], eckey: &EcKeyRef<T>) -> Result<EcdsaSig, ErrorStack>

where T: HasPrivate,

Computes a digital signature of the hash value data using the private EC key eckey.

This corresponds to ECDSA_do_sign.

pub fn from_private_components( r: BigNum, s: BigNum, ) -> Result<EcdsaSig, ErrorStack>

Returns a new EcdsaSig by setting the r and s values associated with an ECDSA signature.

This corresponds to ECDSA_SIG_set0.

pub fn from_der(der: &[u8]) -> Result<EcdsaSig, ErrorStack>

Decodes a DER-encoded ECDSA signature.

This corresponds to d2i_ECDSA_SIG.

Methods from Deref<Target = 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 Deref for EcdsaSig

type Target = EcdsaSigRef

The resulting type after dereferencing.

fn deref(&self) -> &EcdsaSigRef

Dereferences the value.

impl DerefMut for EcdsaSig

fn deref_mut(&mut self) -> &mut EcdsaSigRef

Mutably dereferences the value.

impl Drop for EcdsaSig

fn drop(&mut self)

Executes the destructor for this type.

impl ForeignType for EcdsaSig

type CType = ECDSA_SIG

The raw C type.

type Ref = EcdsaSigRef

The type representing a reference to this type.

unsafe fn from_ptr(ptr: *mut ECDSA_SIG) -> EcdsaSig

Constructs an instance of this type from its raw type.

fn as_ptr(&self) -> *mut ECDSA_SIG

Returns a raw pointer to the wrapped value.

impl Send for EcdsaSig

impl Sync for EcdsaSig

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
