asignify 1.1-1.08af003 Cryptographic authentication and encryption tool and library

Asignify offers public cryptographic signatures and encryption with a library or a command-line tool. The tool is heavily inspired by signify as used in OpenBSD. The main goal of this project is to define a high level API for signing files, validating signatures and encrypting using public-key cryptography. Asignify is designed to be portable and self-contained with zero external dependencies. Asignify can verify OpenBSD signatures, but it cannot sign messages in OpenBSD format yet.
