# Dark Internet Mail Environment (DIME)

## Introduction

Internet electronic mail (email) was designed in the early days of the Internet, and so

lacks any mechanism to protect the privacy of the sender and addressee. Several techniques

have been used in an attempt to increase the privacy of email. These techniques have provided

either modest increases in privacy, or have proven to be very difficult to use for most people.

In addition to protection of content, truly private email must limit information disclosed to 

handling agents, only exposing information necessary for delivery (the metadata), and provide robust

identity guarantees which prevent the impersonation of senders. 

The Dark Internet Mail Environment (DIME) achieves this level of privacy with core protocols

using multiple layers of key management and multiple layers of message encryption. The 

[DIME Protocol Specifications](https://darkmail.info/spec) (PDF, ~20 MB) contain the full technical details of 

the DIME.

The **libdime** project holds the DIME library and associated command line utilities. This code is 

developed in conjunction with the [magma](https://github.com/lavabit/magma) mail daemon, and is 

a community effort to develop and maintain a C library for building DIME compatible software, and

the standalone utilities to test, debug, and administer a DIME compatible mail service.

## Dependencies

Please see the [Quick Start Guide](res/docs/quickstart.md).

System:

c dl rt pthread resolv 

Bundled for DIME:

zlib openssl donna

Bundled for the Unit Tests

googletest gtest-tap-listener

## Supported Platforms

* CentOS 6 x86_64

* CentOS 7 x86_64

## Build Instructions

First, build the bundled dependencies:

    make setup

Then run:

    make all

The specific make targets:

    make dime

    make signet

    make genrec

    make libdime.a

    make libdime.so

Finally, to compile and run the unit tests use:

	make check

	

Or compile the check utility with the make target:

	make dime.check
