Nickserver
==================================

Nickserver is a server running the Nicknym protocol. This daemon can be run by
service providers in order to support Nicknym.

Nicknym is a protocol to map user nicknames to public keys. With Nicknym, the
user is able to think solely in terms of nickname, while still being able to
communicate with a high degree of security (confidentiality, integrity, and
authenticity). Essentially, Nicknym is a system for binding human-memorable
nicknames to a cryptographic key via automatic discovery and automatic
validation.

About nickserver:

* Written in Ruby 2.1, licensed GPLv3
* Lightweight and scalable (high concurrency, reasonable latency)
* Uses asynchronous network IO for both server and client connections (via EventMachine)

API
==================================

You query the nickserver via HTTP. The API is very minimal:

    curl -X POST -d address=alice@domain.org https://nicknym.domain.org:6425

The response consists of a signed JSON document with fields for the available
public keys corresponding to the address.

Requirements
==================================

* Ruby (tested with 2.1.5)
* CouchDB

Installation
==================================

You have three fine options for installing nickserver:

Install prerequisites

    $ sudo apt-get install ruby-dev libssl-dev

Note: libssl-dev must be installed before installing the gem EventMachine,
otherwise the gem will get built without TLS support.

Install from source:

    $ git clone git://leap.se/nickserver
    $ cd nickserver
    $ rake build
    $ rake install

Install for development:

    $ git clone git://leap.se/nickserver
    $ cd nickserver
    $ bundle
    $ rake test

Configuration
==================================

Nickserver loads the configuration files `config/default.yml` and
`/etc/nickserver.yml`, if it exists. See `config/default.yml` for the
available options.

The default HKP host is set to https://hkps.pool.sks-keyservers.net. The CA
for this pool is available here https://sks-keyservers.net/sks-keyservers.netCA.pem

    where COMMAND is one of:
      start         start an instance of the application
      stop          stop all instances of the application
      restart       stop all instances and restart them afterwards
