clang is a breath of fresh air when it comes to deliver meaningful diagnostic of errors in program code. Not only is the diagnostic colourful on screen, clang also points out where in the source file changes ought to be made.
A few days ago I resurrected all my files from a desktop system I haven’t used for almost six years. Below is my implementation of secret splitting as described in Bruce Schneier’s book “Applied Cryptography, 2nd edition”.
The idea is basically: generate a random keystream, xor the plaintext with the random keystream, use separate couriers and send the random keystream and the ciphertext to the final destination using separate routes, and finally combine the random keystream with the ciphertext to recreate the plaintext. None of the couriers know which piece they are carrying.
To improve this idea would be to generate more than one random keystream, xor the keystreams and the plaintext, thus requiring more couriers and different routes for each datastream.

One of my systems is running FreeBSD/amd64 9.0-STABLE and is using ZFS for all its worth. The amount of installed memory in this system is 8 gibibytes, which should be enough to please even ZFS’ ARC. After a few hours of uptime not everyone are happy, and one of those unhappy guys are GnuPG. Continue reading Not enough room for wired pages?→
