Entropy Broker RNG 2.1

Posted Dec 22, 2012

Authored by Folkert van Heusden | Site vanheusden.com

Entropy Broker is an infrastructure for distributing cryptographically secure random numbers (entropy data) from one or more servers to one or more clients. Entropy Broker allows you to distribute entropy data (random values) to /dev/random devices from other systems (real servers or virtualised systems). It helps preventing that the /dev/random device gets depleted; an empty /dev/random-device can cause programs to hang (waiting for entropy data to become available). This is useful for systems that need to generate encryption keys, run VPN software or run a casino website.

Changes: This release adds a Web interface for viewing usage statistics, per-user bandwidth limits, and many small fixes.

Entropy Broker RNG 2.0

This is useful for systems that need to generate encryption keys, run VPN software or run a casino website.

Changes: Entropy broker is now fully multi-threaded so that no client can block the broker, and higher bitrates can now be achieved. The OpenSSL dependency has been replaced by the crypto++ library. A 'configure' script has been added. This release has been checked for software defects with Coverity. The network protocol has been adapted for bigger block sizes. Ciphers/hashes are now fully user selectable. There is reduced broker entropy usage.

LibPRNGWrap 2.0.0

Posted Oct 5, 2011

Authored by Folkert van Heusden | Site vanheusden.com

libprngwrap is a preload-library (so that it doesn't require any changes to the software it alters) which replaces the libc rand() random() and *rand48() calls by code that gets data from /dev/urandom. This might be a little bit more secure.

Changes: This release adds compatibility fixes and implements all re-entrant PRNG functions from libc.

Listener 2.0.1

Posted Aug 2, 2011

Authored by Folkert van Heusden | Site vanheusden.com

This program listens for sound. If it detects any, it starts recording automatically and also automatically stops when things become silent again.

Changes: This version now uses portaudio. This means it is more stable and should run on other platforms (such as Mac OS X). This version also has a new, more flexible commandline format for selecting sample rate and such.

Audio Entropyd /dev/random Feeder

Posted May 3, 2009

Authored by Folkert van Heusden | Site vanheusden.com

audio-entropyd feeds the /dev/random device with entropy data read from an audio device. The audio data is not copied as is, but first 'de-biased' and analyzed to determine how many bits of entropy are in it. This program is useful for systems doing many cryptographic tasks like VPN endpoints or GPG clients; it helps prevent the /dev/random device from being depleted and blocking reads.

Changes: There are major bugfixes. Users are urged to install this release. It also adds ALSA support.
