Cryptographic operations required by commonware-p2p.

Warning

Although data provided to this implementation to be signed are expected to be unique to commonware-p2p, it is strongly recommended to prefix any payloads with a unique identifier (dst) to prevent replay attacks.

Required Methods

fn me(&self) -> PublicKey

Returns the public key of the signer.

fn sign(&mut self, dst: &[u8], data: &[u8]) -> Signature

Sign the given data (usually an IP).

fn validate(public_key: &PublicKey) -> bool

Verify that a public key is well-formatted.

fn verify( dst: &[u8], data: &[u8], public_key: &PublicKey, signature: &Signature, ) -> bool

Check that a signature is valid for the given data and public key.

Object Safety

This trait is not object safe.
