CryptoParty (Crypto-) is a global endeavour to introduce the basics of practical cryptography such as the , , and virtual private networks to the general public. The project primarily consists of a series of free public workshops.

A successor to the Cypherpunks of the 1990s, CryptoParty was conceived in late August 2012 by an Australian privacy advocate (who goes by the Asher Wolf) in a casual conversation with computer security experts following the passage of the Cybercrime Legislation Amendment Bill 2011 and the proposal of a , the Cybercrime Legislation Amendment Bill 2011. The , movement immediately went , with a dozen autonomous CryptoParties being organized within hours in cities throughout Australia, the US, the UK, and Germany.

“When I woke up in the morning, they were all there,” Wolf said in an interview. Asher organised the @cryptoparty Twitter account, paid @hellojaffe to set up the wiki, organised a logo, and promoted the idea, and the need to contribute to the handbook on Twitter. 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  movement- had to be moved from  to the Google campus in east London's . 

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.

CryptoParty has received early messages of support from the and (purportedly) , as well as the , central editor , and reporter . Eric Hughes, the author of A Cypherpunk’s Manifesto nearly two decades before, delivered the keynote address, Putting the Personal Back in Personal Computers, at the Amsterdam CryptoParty on 2012-09-27. , founding member of which in turn founded The Pirate Bay, regards CryptoParty as the most important civic project in cryptography today, and has characterized a CryptoParty as being “like a party for learning crypto.” in December 2014 mentioned “crypto parties” in the wake of the leaks in an article about the .


The first draft of the 442-page CryptoParty Handbook (the hard copy of which is available at cost), was pulled together in three days using the approach, and was released 2012-10-04 under a license; it remains under constant revision.

Attack and site takedown

In April and May 2013, the movement’s main wiki page,, was subject to a series of 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 is not recommended by the ConfirmEdit authors (” […] used by very few wikis outside WMF if any, probably because of scarce effectiveness”).

Edward Snowden involvement

In May 2014, Wired reported that Edward Snowden, while employed by as an NSA contractor, organized a local CryptoParty at a small in , 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.”
