Struct SecretKey 

pub struct SecretKey(/* private fields */);

A secret key.

Implementations

impl SecretKey

pub fn public(&self) -> PublicKey

The public key of this SecretKey.

pub fn generate() -> SecretKey

Generate a new SecretKey with a randomness generator.

This uses the default random number generator from the rand crate. If you want to customize how the randomness is generated, use Self::from_bytes instead and generate the 32 bytes yourself:

// Create a random number generator.
let mut rng = rand::rng();
// Use it to generate the 32 bytes that make up a secret key.
let secret_key = SecretKey::from_bytes(&rng.random());

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

Sign the given message and return a digital signature

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

Convert this to the bytes representing the secret part. The public part can always be recovered.

pub fn from_bytes(bytes: &[u8; 32]) -> SecretKey

Create a secret key from its byte representation.
