While visiting 30c3, I attended the You-broke-the-Internet workshop on NaCl.

One thing mentioned in the talk was that auditing crypto code is a lot of work, and that this is one of the reasons why Ed25519 isn't included in NaCl yet (they promised a version including it for 2014). The speakers mentioned a bug in the amd64 assembly implementation of Ed25519 as an example of a bug that can only be found by auditing, not by randomized tests. This bug is caused by a carry being added in the wrong place, but since that carry is usually zero, the bug is hard to fint (occurs with probability 2^{-60} or so).

The TweetNaCl paper briefly mentions this bug as well:

Partial audits have revealed a bug in this software (r1 += 0 + carry should be r2 += 0 + carry in amd64-64-24k) that would not be caught by random tests; this illustrates the importance of audits.

PSA :

just use GHC for OSX https://ghcformacosx.github.io

the rest of these directions are preserved for historical purposes

TLDR version, if you have homebrew

xcode-select --install ; brew tap homebrew/versions ;   brew tap homebrew/dupes \

Work in progress, I'll write this up properly when I'm done.

Almost all credit goes to @maxogden for putting me on to this and pointing me in the right direction for each of these items.

Prerequisites:

• Raspberry Pi
• Kindle Paperwhite freed from its locked down state (jailbroken) http://www.mobileread.com/forums/showthread.php?t=198446
  • You have to downgrade your Kindle to 5.3.1 to install the current jailbreak; that's just a matter of getting the old version image, putting it on your Kindle via USB and telling it to install "upgrade". Then you put in the Jailbreak files, load the ebook and break.
• Your kindle will be quick to detect an upgrade is available so it'll want to upgrade soon afterwards but the jailbreak will last but you have to reinstall the developer certificates so it's a bit of a pain but doable. Find all the instructions on the mobileread.com forums and wiki.
