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§

source

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
source

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

Verify message digest against the provided signature.
