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: &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
source

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.

Object Safety§

This trait is not object safe.
