[−][src]Trait ecdsa::hazmat::VerifyPrimitive

pub trait VerifyPrimitive<C> where
    C: Curve + ProjectiveArithmetic,
    FieldBytes<C>: From<Scalar<C>> + for<'r> From<&'r Scalar<C>>,
    Scalar<C>: PrimeField<Repr = FieldBytes<C>>,
    SignatureSize<C>: ArrayLength<u8>, {
    fn verify_prehashed(
        &self, 
        hashed_msg: &Scalar<C>, 
        signature: &Signature<C>
    ) -> Result<(), Error>;
}
This is supported on crate features hazmat and 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.

Required methods

fn verify_prehashed(
    &self,
    hashed_msg: &Scalar<C>,
    signature: &Signature<C>
) -> Result<(), Error>

This is supported on crate features hazmat and arithmetic only.

Verify the prehashed message against the provided signature

Accepts the following arguments:

  • verify_key: public key to verify the signature against
  • hashed_msg: prehashed message to be verified
  • signature: signature to be verified against the key and message
