8/// A generic trait that describes a signature scheme.
9///
10/// The general workflow is:
11/// - Instantiating a signature scheme generates a new key pair.
12///   Concrete instantiations have to provide their own way of instantiating
13///   themselves.
14/// - The public key is exposed via `public_key()`
15/// - Messages can be signed using `sign()`
16/// - Signatures can be verified using `verify()`

22    fn sign(&mut self, message: M) -> SIG;

24    /// Verifies a signature.
25    /// Note that this function does not require need `self`, hence does not need
26    /// an instance of the signature scheme.
27    /// This is because an instance of a signature scheme contains the signing key
28    /// which is typically not available for the verifier.
