Struct RustCryptoEcdhKey 

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

Opaque RustCrypto ECDH key with a fixed named-curve domain.

Implementations

impl RustCryptoEcdhKey

pub fn from_scalar( curve: EcdhCurve, bytes: &[u8], ) -> Result<Self, ProviderError>

Import a fixed-width big-endian private scalar. Zero and out-of-range values are rejected, not reduced modulo the curve order.

pub fn public_key(&self) -> Vec<u8>

Export the public SEC1 uncompressed point, never private material.

Trait Implementations

impl Debug for RustCryptoEcdhKey

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl KeyAgreementKey for RustCryptoEcdhKey

fn agree( &self, parameters: &KeyAgreementParameters<'_>, ) -> Result<Vec<u8>, ProviderError>

Derive the raw shared secret for the supplied peer and parameters.

fn dh_domain_bits(&self) -> Option<(usize, usize)>

Public modulus/subgroup bit widths for finite-field DH. Operations use these to recheck key strength under their own policy; no secret is exported.

fn provider_binding(&self) -> Option<&ProviderBinding>

External execution domain, when the private key resides outside this process.
