General Information

===================

This is implementation of Fortuna PRNG (https://en.wikipedia.org/wiki/Fortuna_%28PRNG%29) in C++11 using Boost and Crypto++ libraries, written by Adam Mizerski .

Components:

  - libfortuna          - Implementation of Fortuna algorithm.

  - fortunad            - Daemon which contains Accumulator.

  - libfortuna_daemon   - Libraries implementing communication layer with daemon for entropy sources and clients.

  - fortuna_client      - Client which reads random data from daemon.

Licensing:

  - Libraries (libfortuna, libfortuna_daemon) are released under LGPLv3 or later.

  - Programs (everything else) are released under GPLv3 or later.

Tested with:

  - g++         4.9.2

  - clang++     3.5.0

  - autoconf    2.69

  - automake    1.13.4

  - libtool     2.4.2

  - Boost       1.54.0

  - Crypto++    5.6.2

Notes about libfortuna

======================

  - You must provide the seed file. For example by 'dd if=/dev/random of=./fortuna.seed bs=64 count=1'. Please note that it's not safe when done at first boot on a virtual machine without entropy provided by host.

  - SHA3 (Keccak) is used instead of double SHA2.

  - Random data is generated in blocks of bytes. User must allocate enough memory to store whole blocks.

    In Accumulator there are output_block_length variable and bytes_to_blocks method, which helps with this task.
