This is my homepage. You're probably looking for some software I've written. Most of the software I've written are heavily related to information security. I'm active also on IRC as sarthalion@LiberaChat.
I've written a lot of software during the years, but here are the most useful ones. These are in active development.
Wilhelmina is a password manager. It's an open source (licensed under GPLv3+) software. Source code is available on Github. It's written for Windows, but should be fairly portable to other operating systems.
Wilhelmina has an IRC channel on LiberaChat. Welcome to #wilhelmina.
Wilhelmina has it's own website in here.
SECRET is a cross platform, command line, file encryption program. It allows secure file and directory encryption from the command line. SECRET also includes SecretEngine.dll library which is an easy to use file encryption library for .NET.
SECRET is licensed under the MIT open source license. Source code is available on Github.
Download version 1.6 precompiled binary for Windows or for Linux and see SECRET manual (pdf) for usage. It also explains technical details about the encryption algorithms in SECRET.
SECRET is also available from FOSSHUB.
Both binaries for Windows and for Linux are standalone builds they do not need .NET to run.
SECRET has an IRC channel, welcome to #secretapp@LiberaChat.
