Struct SecretKey 

pub struct SecretKey { /* private fields */ }

Available on crate feature eddsa only.

An Ed25519 private key usable for signing.

Implementations

impl SecretKey

pub fn generate() -> SecretKey

Creates a new, random private key.

pub fn from_bytes(bin: &[u8; 32]) -> Self

Converts a 32-byte array into a private key.

pub fn from_der(der: &[u8]) -> Result<Self, Error>

Parses a DER buffer into a private key.

pub fn from_pem(pem_str: &str) -> Result<Self, Error>

Parses a PEM string into a private key.

pub fn to_bytes(&self) -> Zeroizing<[u8; 32]>

Converts a private key into a 32-byte array.

pub fn to_der(&self) -> Zeroizing<Vec<u8>>

Serializes a private key into a DER buffer.

pub fn to_pem(&self) -> Zeroizing<String>

Serializes a private key into a PEM string.

pub fn public_key(&self) -> PublicKey

Retrieves the public counterpart of the secret key.

pub fn fingerprint(&self) -> Fingerprint

Returns a 256-bit unique identifier for this key. For Ed25519, that is the SHA256 hash of the raw public key.

pub fn sign(&self, message: &[u8]) -> Signature

Creates a digital signature of the message.

Trait Implementations

impl Clone for SecretKey

fn clone(&self) -> Self

Returns a duplicate of the value.

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