Trait ecdsa::hazmat::FromDigest

pub trait FromDigest<C: Curve> {
    fn from_digest<D>(digest: D) -> Self
    where
        D: Digest<OutputSize = FieldSize<C>>;
}

This is supported on crate features hazmat and digest only.

Instantiate this type from the output of a digest.

This trait is intended for use in ECDSA and should perform a conversion which is compatible with the rules for calculating h from H(M) set out in RFC6979 section 2.4. This conversion cannot fail.

This trait may also be useful for other hash-to-scalar or hash-to-curve use cases.

Required methods

fn from_digest<D>(digest: D) -> Self where
    D: Digest<OutputSize = FieldSize<C>>, 

Instantiate this type from a [Digest] instance

Implementations on Foreign Types
