### edwards25519-extra

This package provides extensions to the Go standard library's Ed25519 and
curve25519 implementations, primarily extracted from [curve25519-voi][1].
This package is intended for interoperability with the standard library
and the [edwards25519][2] package as much as possible.

 * h2c: [Hashing to Elliptic Curves (version 16)][3]
 * vrf: [Verifiable Random Functions (version 10, 13)][4]

Note: It is the author's biased opinion that using curve25519-voi is
objectively superior to using the standard library along with this
package.
