Trait SignatureScheme 

Source 
pub trait SignatureScheme<PK, M, SIG> {
    // Required methods
    fn public_key(&self) -> PK;
    fn sign(&mut self, message: M) -> SIG;
    fn verify(pk: PK, message: M, signature: &SIG) -> bool;
}
Expand description

A generic trait that describes a signature scheme.

The general workflow is:

  • Instantiating a signature scheme generates a new key pair. Concrete instantiations have to provide their own way of instantiating themselves.
  • The public key is exposed via public_key()
  • Messages can be signed using sign()
  • Signatures can be verified using verify()

Required Methods§

Source

fn public_key(&self) -> PK

Returns a copy of the public key

Source

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

Signs a message

Source

fn verify(pk: PK, message: M, signature: &SIG) -> bool

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

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
