  • Enchive : encrypted personal archives, by Chris Wellons (https://nullprogram.com/)
    Enchive is a tool to encrypt files to yourself for long-term archival. It's a focused, simple alternative to more complex solutions such as GnuPG or encrypted filesystems. Enchive has no external dependencies and is trivial to build for local use. Portability is emphasized over performance.

    Supported platforms: Linux, BSD, macOS, Windows

    The name is a portmanteau of "encrypt" and "archive," pronounced en'kīv.

    Files are secured with ChaCha20, Curve25519, and HMAC-SHA256.

    Key pairs can be derived from a pass phrase.  See https://github.com/skeeto/passphrase2pgp for a tool to generate gpg key pairs in a similar way.

  • The Original Hacker's Dictionary
    This file, jargon.txt, was maintained on MIT-AI for many years, before being published by Guy Steele and others as the Hacker's Dictionary. Many years after the original book went out of print, Eric Raymond picked it up, updated it and republished it as the New Hacker's Dictionary. Unfortunately, in the process, he essentially destroyed what held it together, in various ways: first, by changing its emphasis from Lisp-based to UNIX-based (blithely ignoring the distinctly anti-UNIX aspects of the LISP culture celebrated in the original); second, by watering down what was otherwise the fairly undiluted record of a single cultural group through this kind of mixing; and third, by adding in all sorts of terms which are "jargon" only in the sense that they're technical. This page, however, is pretty much the original, snarfed from MIT-AI around 1988. -- jpd.
