Struct RustCryptoDhKey 

pub struct RustCryptoDhKey { /* private fields */ }

Finite-field DH handle with validated prime-order domain parameters. Private scalars and shared secrets are never exposed by Debug.

Implementations

impl RustCryptoDhKey

pub fn from_components( provider: &dyn CryptoProvider, budget: &mut KeyEstablishmentBudget<'_>, p: &[u8], q: &[u8], generator: &[u8], private: &[u8], ) -> Result<Self, XmlEncError>

Import unsigned big-endian p/q/g and private x. Validation is charged to the supplied operation before allocating big integers or testing primes. The provider supplies independent random Miller-Rabin bases; failures are propagated, never replaced with deterministic or biased bases.

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

Export the public value with the same fixed octet width as p.

Trait Implementations

impl Debug for RustCryptoDhKey

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

Formats the value using the given formatter.

impl KeyAgreementKey for RustCryptoDhKey

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

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

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

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