Function coins_bip32::ecdsa::hazmat::verify_prehashed

pub fn verify_prehashed<C>(
    q: &<C as CurveArithmetic>::ProjectivePoint,
    z: &GenericArray<u8, <C as Curve>::FieldBytesSize>,
    sig: &Signature<C>
) -> Result<(), Error>where
    C: PrimeCurve + CurveArithmetic,
    <<C as Curve>::FieldBytesSize as Add<<C as Curve>::FieldBytesSize>>::Output: ArrayLength<u8>,

Verify the prehashed message against the provided ECDSA signature.

Accepts the following arguments:

• q: public key with which to verify the signature.
• 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.
