Trait PrehashVerifier 

pub trait PrehashVerifier<S> {
    // Required method
    fn verify_prehash(&self, prehash: &[u8], signature: &S) -> Result<(), Error>;
}

Verify the provided message prehash using Self (e.g. a public key)

Required Methods

fn verify_prehash(&self, prehash: &[u8], signature: &S) -> Result<(), Error>

Use Self to verify that the provided signature for a given message prehash is authentic.

The prehash parameter MUST be the output of a secure cryptographic hash function.

Security Warning

If prehash is something other than the output of a cryptographically secure hash function, an attacker can potentially forge signatures by e.g. solving a system of linear equations.

Returns Ok(()) if the signature verified successfully.

Errors

Returns Error in the event the signature fails to verify or if prehash is an invalid length.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
