CryptoParty Handbook!

  • The CryptoParty Handbook tries to provide a comprehensive guide to the various topics that might come up while investigating the realms of computer and internet security and is designed to be a practical guide during Cryptoparties.

Don't take any wooden nickels!

  • You should Always check the cryptographic hash of downloaded files using commands like “SHA256SUM” and compare the hashes you get with thost provided by the server where you downloaded the file.
  • Even better would be to double check this result against multiple authoritative and trusted sources
  • With open source software that can be compiled by anyone with a computer, this process of network verification of a binary has become easier in resent years.
  • For greatest effect, hashing of a download can be distributed and verified by very large group online in order to achiveve a consensus about the hash for a particular binary at a particular time.
  • Currently this process is manual but there have been some efforts to standardise and automate the way we check the integrity of downloaded files.
  • The following handbook files have been hashed using SHA256SUM as a post build step after “make install” is run on the handbook source code, the results of which are below:

  • Download SHA256SUM

Get the Saucecode

  • The best way to be sure that the contents of the handbook are up to date and unaltered from the source code is to grab the source code and compile the handbook yourself: github

Get the Handbook

  • If that sounds a little bit too hardcore for you then you can also download the handbook as .pdf .mobi .epub or .md

CryptoPartyHandbook for Kindle

  • We are thrilled to announce that the Cryptoparty Handbook is now Kindle-friendly. Please download .mobi .cover.jpg and metadata.opf and place all three files into your Calibre Library

Old Versions

snapshot version 1.1 is downloadable as PDF and ePub.

  • The SHA256 checksums for the files are “e8d05c9693930dc942200546389eb12673da44647f62f6d22dbe07f35c9f6cd8” and “798e16edec4c4fa973d73bcbae85f6a1a73c49fa158cb1ac6a0b0863b2997f62” respectively.
  • It is based on the open source books “Basic Internet Security” and “How to Bypass Internet Censorship”
