Halibut is a documentation production system, with elements similar to TeX,
debiandoc-sgml, TeXinfo, and others. It is primarily targeted at people
producing software manuals.

Bound Book Format (.bbf) is a high-performance binary container designed
specifically for digital comic books and manga. Unlike CBR/CBZ, BBF is built
for DirectSotrage/mmap, easy integrity checks, and mixed-codec
containerization.

This program computes odd for drawing card sets (e.g. non-replacement
probabilities) using the hypergeometric function. It can also be used to
compute binomial coefficients and the gamma function.

Efficient computation of scattering form factors (Fourier shape transforms) of
arbitrary polyhedra according to Wuttke, J Appl Cryst 54, 580-587 (2021).

Header-only C++ base library of Heinz Maier-Leibnitz Zentrum.

The miniSEED library provides a framework for manipulation of miniSEED records,
a format commonly used for seismological time series and related data. The
library includes the functionality to read and write data records, in addition
to reconstructing time series from multiple records.

A command-line and terminal interface for browsing the On-Line Encyclopedia of
Integer Sequences (OEIS).

bkcrack is a command-line tool which implements a known plaintext attack
against legacy encrypted ZIP archives. The vulnerability was shown by Eli Biham
and Paul C. Kocher in the research paper "A known plaintext attack on the PKZIP
stream cipher." The main features are:

* Recover internal state from ciphertext and plaintext.
* Remove or change a ZIP archive's password using the internal state.
* Recover the original password from the internal state.

crackpkcs12 is a tool to audit PKCS#12 files passwords (extension .p12 or
.pfx). It's written in C and uses openssl library.

EncFS provides an encrypted file system, layered on top of a normal
directory tree and encrypts individual files which are stored in the
hosting directory tree.

This has several advantages over the loopback encryption which
provided by the Linux kernel:
- No space is and has to be reserved, encrypted files only
take the space that they really occupy
- Backups: encrypted files can be individually backed-up on the host
filesystem
- Layering: Since it's hosted on a normal filesystem, encfs can be
used on filesystems which normally have no support encryption,
like NFS or other userspace filesystems.

EncFS is implemented as a userspace filesystem in an unprivileged
application using fuse (FUSE (Filesystem in USErspace)).
