Struct openssl::ecdsa::EcdsaSig

pub struct EcdsaSig(_);

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.

OpenSSL documentation at 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 a ECDSA signature.

OpenSSL documentation at 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.

pub fn r(&self) -> &BigNumRef

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

OpenSSL documentation at ECDSA_SIG_get0

pub fn s(&self) -> &BigNumRef

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