Some Go cryptography routines that are not included in the Go standard library

 This repository contains Go packages related to cryptographic standards
 that are not included in the Go standard library. These include:
 • SIV mode (http://go.pkgdoc.org/github.com/jacobsa/crypto/siv),
  which provides deterministic encryption with authentication.
 • CMAC (http://go.pkgdoc.org/github.com/jacobsa/crypto/cmac),
  a message authentication system used by SIV mode.
