Free Software Projects

Here are some free software programs I have developed. I had a need for each of them (or an “itch”, as Eric S. Raymond would say), so maybe they can have some use for someone else.

• Asysex – A SysEx utility
• Adfgvx – ADFGVX ciphering tool
• Bioutils – Utilities for computational biology
• Certbot-SSH – SSH authenticator plugin for Certbot
• Fmail – Mail formatter
• Gfsecret – Secret sharing tools
• Kmxtool – KORG microX utility
• Pebble – Command-line client for Nextcloud’s Passman
• Pyplot – Helper plotting library for Python and Matplotlib
• Scdtools – Tools for Scdaemon and OpenPGP smartcards
• Scorepw – A password strength meter
• Ulimits – User limits utility
• Wait4 – Wait for an arbitrary process
• Xdna2 – DNA Strider file format utility
• Yorkie – A task-oriented GnuPG frontend

In addition, here are some older projects that I don’t develop anymore.
