}

Verify the given prehashed message using ECDSA.

This trait is intended to be implemented on type which can access the affine point represeting the public key via &self, such as a particular curve’s AffinePoint type.

Provided Methods

fn verify_prehashed( &self, z: &GenericArray<u8, <C as Curve>::FieldBytesSize>, sig: &Signature<C> ) -> Result<(), Error>

Verify the prehashed message against the provided ECDSA signature.

Accepts the following arguments:

• z: message digest to be verified. MUST BE OUTPUT OF A CRYPTOGRAPHICALLY SECURE DIGEST ALGORITHM!!!
• sig: signature to be verified against the key and message

fn verify_digest<D>( &self, msg_digest: D, sig: &Signature<C> ) -> Result<(), Error>where D: FixedOutput<OutputSize = <C as Curve>::FieldBytesSize>,

Verify message digest against the provided signature.
