Struct Keys

pub struct Keys {
    pub sk: SecretKey,
    pub pk: PublicKey,
}

A c25519 keypair, to sign or verify messages.

There’s no particular advantage to using this instead of SecretKey and PublicKey seperately, but it may be convenient to keep track of them as a single unit.

Fields

sk: SecretKey

The secret key.

pk: PublicKey

The public key.

Implementations

impl Keys

pub fn verify_domain( &self, domain: Domain, sig: &Signature, msg: &[u8], ) -> Result<(), Error>

Verify a message in a particular domain.

pub fn sign_domain(&self, domain: Domain, msg: &[u8]) -> Signature

Sign a message for a particular domain, with a derived nonce.

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

Sign a message for the default domain.

pub fn verify(&self, sig: &Signature, msg: &[u8]) -> Result<(), Error>

Verify a message in the default domain.

pub fn sign_nonce( &self, domain: Domain, nonce: &[u8; 32], msg: &[u8], ) -> Signature

Sign a message for a particular domain, with the supplied secret nonce.

If you really want randomized signatures, this is the function to use. Make sure you have a really solid random number generator making these nonces!

Trait Implementations

impl Clone for Keys

fn clone(&self) -> Keys

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Keys

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

Formats the value using the given formatter.
