Available on (crate features ecdsa or sha256) and crate feature hazmat and crate feature ecdsa-core and crate feature arithmetic only.

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>,

Available on crate feature digest only.

Verify message digest against the provided signature.

Object Safety

This trait is not object safe.

Implementors

impl VerifyPrimitive<Secp256k1> for AffinePoint

Available on crate feature ecdsa only.
