Gopaque implements the OPAQUE protocol in Go. OPAQUE is a way to register users with a server without having to send the user's password to the server during registration or authentication. An introduction to OPAQUE (and PAKEs in general) can be found at this article: Let's talk about PAKE. Gopaque uses the Kyber library to implement this pending RFC using elliptic curves.
To install:

The documentation, API, and examples are in the Godoc.
