psignify

psignify
========

This is a portable implementation of OpenBSD's signify[1]. Right now,
it supports generating and verifying detached signatures and keypair
generation.

There is initial support for nacl/box encryption using the libsodium
Ed25519 -> Curve25519 keypair conversion[2]. There isn't a mechanism
now for encrypting while I figure out a good format for this.
