}

Trait impl’d by public keys in asymmetric cryptography.

The trait bounds are implemented so as to be symmetric and equivalent to the ones on its associated types for private and signature material.

Required Associated Constants

const LENGTH: usize

Required Associated Types

type PrivKey: SigningKey<PubKey = Self>

type Sig: Authenticator<PubKey = Self>

Required Methods

fn verify( &self, msg: &[u8], signature: &Self::Sig, ) -> Result<(), FastCryptoError>

Use Self to verify that the provided signature for a given message bytestring is authentic. Returns Error if it is inauthentic, or otherwise returns ().

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.
