hash_to_field

Documentation

Overview

Package htf provides hasher based on RFC 9380 Section 5.

The RFC 9380 defines a method for hashing bytes to elliptic curves. Section 5 of the RFC describes a method for uniformly hashing bytes into a field using a domain separation. The hashing is implemented in [fp], but this package provides a wrapper for the method which implements hash.Hash for using the method recursively.

Functions

func New

func New(domainSeparator []byte) hash.Hash

New returns a new hasher instance which uses fr.Hash to hash all the written bytes to a field element, returning the byte representation of the field element. The domain separator is passed as-is to hashing method.
