only.Expand description
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: FieldBytes<C>, sig: &Signature<C>) -> Result<()>
fn verify_prehashed(&self, z: FieldBytes<C>, sig: &Signature<C>) -> Result<()>
Verify the prehashed message against the provided 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
