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 a 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.
