[−][src]Trait ecdsa::hazmat::RecoverableSignPrimitive
This is supported on crate features
hazmat
and arithmetic
only.SignPrimitive
for signature implementations that can provide public key
recovery implementation.
Required methods
pub fn try_sign_recoverable_prehashed<K: Borrow<Scalar<C>> + Invert<Output = Scalar<C>>>(
&self,
ephemeral_scalar: &K,
hashed_msg: &Scalar<C>
) -> Result<(Signature<C>, bool), Error>
[src]
&self,
ephemeral_scalar: &K,
hashed_msg: &Scalar<C>
) -> Result<(Signature<C>, bool), Error>
Try to sign the prehashed message.
Accepts the same arguments as SignPrimitive::try_sign_prehashed
but returns a boolean flag which indicates whether or not the
y-coordinate of the computed 𝐑 = 𝑘×𝑮 point is odd, which can be
incorporated into recoverable signatures.
