Struct EdDsaPrivateKey 

pub struct EdDsaPrivateKey { /* private fields */ }

Private key for the Edwards-curve signature layer.

Implementations

impl EdDsaPrivateKey

pub fn curve(&self) -> &TwistedEdwardsCurve

Return the curve parameters.

pub fn private_scalar(&self) -> &BigUint

Return the private scalar d ∈ [1, n).

pub fn public_point(&self) -> &EdwardsPoint

Return the cached public point A = d·G.

pub fn to_public_key(&self) -> EdDsaPublicKey

Derive the matching public key A = d·G.

pub fn sign_message_with_nonce<H: Digest>( &self, message: &[u8], nonce: &BigUint, ) -> Option<EdDsaSignature>

Sign with an explicit nonce scalar k.

Reusing the same nonce with the same private key leaks the secret scalar from two signatures, so this entry point is for deterministic tests and fixed vectors only.

pub fn sign_message<H: Digest, R: Csprng>( &self, message: &[u8], rng: &mut R, ) -> Option<EdDsaSignature>

Sign using a fresh random nonce.

pub fn sign_message_bytes<H: Digest, R: Csprng>( &self, message: &[u8], rng: &mut R, ) -> Option<Vec<u8>>

Sign and serialize in one step.

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

Encode the private key in the crate-defined binary format.

Field layout: [p, a, d, n, Gx, Gy, private].

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

Decode a private key from the crate-defined binary format.

pub fn to_pem(&self) -> String

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

pub fn to_xml(&self) -> String

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

Trait Implementations

impl Clone for EdDsaPrivateKey

fn clone(&self) -> EdDsaPrivateKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdDsaPrivateKey

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

Formats the value using the given formatter.

impl PartialEq for EdDsaPrivateKey

fn eq(&self, other: &Self) -> 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.
