Swish-e is Simple Web Indexing System for Humans - Enhanced. Swish-e can quickly and easily index directories of files or remote web sites and search the generated indexes.

Omega is a search application built on Xapian. It provides indexers and a CGI web search frontend.

Dataparksearch is a full featured web search engine. It has support for HTTP, HTTPS, ftp (passive mode), NNTP and news URL schemes, and other URL schemes with external parsers. It can tweak URLs with session IDs and other weird formats, including some JavaScript link decoding. Options to query with all words, all words near to each others, any words, or boolean queries. A subset of VQL (Verity Query Language) is supported.

Tocc is a tag-based file management system. This package contains the command line tool for interacting with libtocc.

GNU Bool is a utility to perform text searches on files using Boolean expressions. For example, a search for "hello AND world" would return a file containing the phrase "Hello, world!". It supports both AND and OR statements, as well as the NEAR statement to search for the occurrence of words in close proximity to each other. It handles context gracefully, accounting for new lines and paragraph changes. It also has robust support for parsing HTML files.

Plocate is a locate based on posting lists, completely replacing mlocate with a faster and smaller index. It is suitable as a default locate on your system.

Xapers is a personal document indexing system, geared towards academic journal articles build on the Xapian search engine. Think of it as your own personal document search engine, or a local cache of online libraries. It provides fast search of document text and bibliographic data and simple document and bibtex retrieval.

mlocate is a locate/updatedb implementation. The m stands for "merging": updatedb reuses the existing database to avoid rereading most of the file system, which makes it faster and does not trash the system caches as much. The locate(1) utility is intended to be completely compatible with slocate, and attempts to be compatible to GNU locate when it does not conflict with slocate compatibility.

Recoll finds documents based on their contents as well as their file names. It can search most document formats, but you may need external applications for text extraction. It can reach any storage place: files, archive members, email attachments, transparently handling decompression.

Ugrep is a ultra fast searcher of file systems, text and binary files, source code, archives, compressed files, documents, and more.

While still being compatible with the standard GNU/BSD grep command-line options, ugrep supports fuzzy search as well as structured and (adjustable) colored output, piped through "less" for pagination. An interactive query UI allows refinement and has a built-in help (press F1). Ugrep implements multi-threaded and other techniques to speed up search, pattern-matching and decompression. Many pre-defined regexps ease searching e.g. C typdefs or XML attributes. Results can be output in several structured or self-defined formats.

Recoll finds documents based on their contents as well as their file names. It can search most document formats, but you may need external applications for text extraction. It can reach any storage place: files, archive members, email attachments, transparently handling decompression.

Search::Xapian wraps most methods of most Xapian classes. The missing classes and methods should be added in the future. It also provides a simplified, more 'perlish' interface to some common operations.

libtocc is the engine of the Tocc project, a tag-based file management system. The goal of Tocc is to provide a better system for classifying files that is more flexible than classic file systems that are based on a tree of files and directories.

Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also supports a rich set of boolean query operators.

Python library and command line tool for configuring a YubiKey. Note that after installing this package, you might still need to add appropriate udev rules to your system configuration to be able to configure the YubiKey as an unprivileged user.

YubiKey Manager (Qt) is a graphical application for configuring any YubiKey over all USB interfaces. For a CLI alternative, refer to the python-yubikey-manager package.

Libu2f-host provides a C library and command-line tool that implements the host-side of the Universal 2nd Factor (U2F) protocol. There are APIs to talk to a U2F device and perform the U2F Register and U2F Authenticate operations.

This is an OpenSSL provider to access hardware and software tokens using the PKCS#11 cryptographic token interface. Access to tokens depends on loading an appropriate PKCS#11 driver that knows how to talk to the specific token. The PKCS#11 provider is a connector that allows OpenSSL to make proper use of such drivers.

This package provides the pcsc_scan, ATR_analysis, scriptor, and gscriptor commands, which are useful tools to test a PC/SC driver, card or reader or send commands in a friendly environment (text or graphical user interface).

Yubikey-oath-demenu lets you pick an OATH credential from your YubiKey using dmenu, and copies the corresponding OTP to the clipboard. Alternatively, it can "type" the OTP using xdotool on X11.

Notable features:

• Pick between all credentials on all connected YubiKeys

• No mouse interaction required

SoftHSM 2 is a software implementation of a generic cryptographic device with a PKCS #11 Cryptographic Token Interface.

This package provides GUI tool that interfaces with Nitrokey Pro v0.7/v0.8 and Nitrokey Storage devices.

This package provides a communication library for Nitrokey.

This package includes the IFD driver for the cyberJack contactless (RFID) and contact USB chipcard readers.
