A successor to the Cypherpunks of the 1990s, CryptoParty was conceived in late August 2012 by the Australian journalist Asher Wolf in a Twitter post following the passing of the Cybercrime Legislation Amendment Bill 2011 and the proposal of a two-year data retention law in that country, the Cybercrime Legislation Amendment Bill 2011. The DIY, self-organizing movement immediately went viral, with a dozen autonomous CryptoParties being organized within hours in cities throughout Australia, the US, the UK, and Germany. Many more parties were soon organized or held in Chile, The Netherlands, Hawaii, Asia, etc. Tor usage in Australia itself spiked, and CryptoParty London with 130 attendees—some of whom were veterans of the Occupy London movement—had to be moved from London Hackspace to the Google campus in east London's Tech City. As of mid-October 2012 some 30 CryptoParties have been held globally, some on a continuing basis, and CryptoParties were held on the same day in Reykjavik, Brussels and Manila.
The first draft of the 442-page CryptoParty Handbook was pulled together in three days using the book sprint approach, and was released 2012-10-04 under a CC-BY-SA license; it remains under constant revision.
Attack and site takedown
In April and May 2013, the movement's main wiki page, cryptoparty.org, was subject to a series of spam attacks that eventually resulted in the site being taken out of service. Protection against spam attacks was rendered more difficult than on other wikis by a site-specific policy permitting edits from users employing anonymization services. Spam attacks were also facilitated by the use of inappropriate MediaWiki settings in ConfirmEdit plugin. The use of SimpleCaptcha is not recommended by the ConfirmEdit authors.
In May 2014, Wired reported that Edward Snowden, while employed by Dell as an NSA contractor, organized a local CryptoParty at a small hackerspace in Honolulu, Hawaii on December 11, six months before becoming well known for leaking tens of thousands of secret U.S. government documents. During the CryptoParty, Snowden taught 20 Hawaii residents how to encrypt their hard drives and use the Internet anonymously. The event was filmed by Snowden's then-girlfriend, but the video has never been released online. In a follow-up post to the CryptoParty wiki, Snowden pronounced the event a "huge success."
