Trait NormalizeLow

pub trait NormalizeLow: Sized {
    // Required method
    fn normalize_low(&self) -> Option<Self>;
}

Normalize a scalar (i.e. ECDSA S) to the lower half the field, as described in BIP 0062: Dealing with Malleability.

Required Methods

fn normalize_low(&self) -> Option<Self>

Normalize scalar to the lower half of the field (i.e. negate it if it’s larger than half the curve’s order).

Returns an Option with a new scalar if the original wasn’t already low-normalized.

May be implemented to work in variable time.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
