    Kashyyyk

    Kashyyyk

    A Work-In-Progress, Full-Featured, Open Source IRC Client

    Kashyyyk is full featured, open source, cross platform IRC client. It was originally written to replace HexChat on OS X. At the time, HexChat (a fork of XChat) had only had a single release on OS X, which was still in alpha. Kashyyyk is extremely small, the binaries and related libraries totaling around half a megabyte. Kashyyyk also has very few external dependencies, the official binaries statically linking all supporting libraries. Kashyyyk is natively available for OS X, Windows, and FreeBSD. Additionally, it can be compiled for Cygwin/X. When possible, Kashyyyk takes advantage of native OS capabilites, such as the OS X notification center. Kashyyyk uses the libfjirc library originally written for the Whittler IRC bot and the libfjnet wrapper written for TurboSphere. It has an FLTK-based GUI. Kashyyyk is intended to be cross platform and easily compiled. It is known to compile using Clang, GCC, Cygwin, Sun Studio, and MSVC 2013.

    The MOTET Cipher & SE Scrambler

    The MOTET Cipher & SE Scrambler

    A tiny, fast encryption tool in C

    MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that each ciphertext will differ radically from every other, even on the same message and identical key.
