Struct PrivateKey 

pub struct PrivateKey<C: Curve> { /* private fields */ }

An ECDSA private key over the given curve.

Implementations

impl<C: Curve> PrivateKey<C>

pub fn generate() -> Self

Generate a random private key.

pub fn from_big_endian(scalar: &[u8]) -> Option<Self>

Parse a PrivateKey from a zero-padded, big-endian representation of the secret scalar.

pub fn to_big_endian(&self) -> Buffer

Return the private key as zero-padded, big-endian bytes.

pub fn from_der_ec_private_key(der: &[u8]) -> Option<Self>

Parse an ECPrivateKey structure (from RFC 5915). The key must be on the specified curve.

pub fn to_der_ec_private_key(&self) -> Buffer

Serialize this private key as an ECPrivateKey structure (from RFC 5915).

pub fn from_der_private_key_info(der: &[u8]) -> Option<Self>

Parse a PrivateKeyInfo structure (from RFC 5208), commonly called “PKCS#8 format”. The key must be on the specified curve.

pub fn to_der_private_key_info(&self) -> Buffer

Serialize this private key as a PrivateKeyInfo structure (from RFC 5208), commonly called “PKCS#8 format”.

pub fn to_x962_uncompressed(&self) -> Buffer

Serialize the public part of this key in uncompressed X9.62 format.

pub fn to_x962_compressed(&self) -> Buffer

Serialize the public part of this key in compressed X9.62 format.

WARNING: compressed form is rarely used and is not as well supported as the uncompressed form.

pub fn to_der_subject_public_key_info(&self) -> Buffer

Serialize this key in SubjectPublicKeyInfo format.

pub fn to_public_key(&self) -> PublicKey<C>

Return the public key corresponding to this private key.

pub fn sign(&self, to_be_signed: &[u8]) -> Vec<u8>

Sign a digest of to_be_signed using this key and return the ASN.1-based signature. SHA-256 will be used to produce the digest if the curve of this public key is P-256. SHA-384 will be used to produce the digest if the curve of this public key is P-384.

pub fn sign_p1363(&self, to_be_signed: &[u8]) -> Vec<u8>

Sign a digest of to_be_signed using this key and return the P1363-based signature. SHA-256 will be used to produce the digest if the curve of this public key is P-256. SHA-384 will be used to produce the digest if the curve of this public key is P-384.

Trait Implementations

impl<C: Curve> Clone for PrivateKey<C>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
