Cypherpunk

The cypherpunks were an informal group of people interested in privacy and cryptography who originally communicated through the cypherpunks mailing list. The aim of the group was to achieve privacy and security through proactive use of cryptography.

In its heyday in the late 90s, the list discussed the public policy issues related to cryptography, as well as more practical nuts-and-bolts mathematical, computational, technological, and cryptographic matters themselves. At that time, it was a very active list; traffic averaged about 200 messages a day, divided between personal arguments and attacks, political discussion, and technical discussion, with some spam thrown in.

The list had a variety of viewpoints and many rather heated discussions, but there was a overall attitude exemplified in these quotes from Tim May's Cypherpunk Manifesto:

There was also very much a feeling of an Us against Them battle, that cypherpunks were fundamentally opposed to many government policies on cryptography. As May put it in the Manifesto " Cypherpunks deplore regulations on cryptography, for encryption is fundamentally a private act." John Gilmore, whose site hosted the original cypherpunks list, wrote:

A coderpunks list, open by invitation only, existed for a time. Coderpunks took up more technical matters and had less discussion of public policy implications.

The term cypherpunk, derived from cipher and punk, was coined by Wired magazine writer Jude Milhon at one of the early cypherpunk gatherings, as a pun to describe cyberpunks who used cryptography.

Other uses
Cypherpunk, cypherpunks or cpunks are also occasionally used as a username and password on websites which require registration, especially if the user does not intend to return or does not wish to reveal information about himself. The account is left for later users. As of 2007, username "cypherpunks01" with password "cypherpunks01" seems to be one of the few of these "public use accounts" which seems to be widely available.
