Implementations

impl SecretKey

pub fn algorithm(&self) -> Algorithm

Returns the signing algorithm.

pub fn from_bytes( algorithm: Algorithm, bytes: &[u8], ) -> Result<SecretKey, Error>

Creates a secret key from a byte sequence for a given signing algorithm.

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

Returns a byte sequence representing the secret key.

pub fn public_key(&self) -> PublicKey

Returns the public key used for verifying signatures.

pub fn sign(&self, msg: &[u8], context_param: &str) -> Signature

Signs a message and returns it’s signature.

pub fn sign_prehashed(&self, hash: &[u8]) -> Result<Signature, Error>

Signs a prehashed message and returns it’s signature.
