Struct DhPrivateKey 

pub struct DhPrivateKey { /* private fields */ }

Private key for DH.

Implementations

impl DhPrivateKey

pub fn modulus(&self) -> &BigUint

pub fn subgroup_order(&self) -> &BigUint

pub fn generator(&self) -> &BigUint

pub fn exponent(&self) -> &BigUint

The private exponent x ∈ [1, q).

pub fn to_public_key(&self) -> DhPublicKey

Derive the matching public key.

pub fn params(&self) -> DhParams

pub fn agree_element(&self, peer: &DhPublicKey) -> Option<BigUint>

Compute the shared secret with a peer’s public key.

Returns s = y_peer^x mod p, or None if the peer key uses different domain parameters or fails subgroup validation.

Subgroup validation: checks that 1 < y_peer < p and that y_peer^q ≡ 1 mod p, rejecting low-order and small-subgroup inputs.

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

Encode in binary format: [p, q, g, x].

pub fn from_key_blob(blob: &[u8]) -> Option<Self>

Decode from binary format.

pub fn to_pem(&self) -> String

pub fn from_pem(pem: &str) -> Option<Self>

Returns None if the PEM label does not match or the payload is malformed.

pub fn to_xml(&self) -> String

pub fn from_xml(xml: &str) -> Option<Self>

Returns None if the XML is malformed or x is zero or ≥ q.

Trait Implementations

impl Clone for DhPrivateKey

fn clone(&self) -> DhPrivateKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DhPrivateKey

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

Formats the value using the given formatter.

impl PartialEq for DhPrivateKey

fn eq(&self, other: &DhPrivateKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
