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.
