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

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.

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.

Hyper Estraier can be used to integrate full-text search into applications, using either the provided command line and CGI interfaces, or a C API.

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.

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.

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

FSearch is a fast file search utility, inspired by Everything Search Engine. It is written in C and based on GTK3.

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.

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.

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.

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.

libfido2 provides library functionality and command-line tools to communicate with a FIDO device over USB, and to verify attestation and assertion signatures.

libfido2 supports the FIDO U2F (CTAP 1) and FIDO 2.0 (CTAP 2) protocols.

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

This package contains a C library and command-line tools that make up the low-level development kit for the Yubico YubiKey authentication device.

YubiKey C Client Library (libykclient) is a C library used to validate a one-time-password (OTP) YubiKey against Yubico’s servers. See the Yubico website for more information about Yubico and the YubiKey.

This application provides support for using private and governmental e-services, signing and encrypting DigiDoc documents, and configuring Estonian ID cards. It requires a running pcscd service and a compatible card reader.

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

Cardpeek is a graphical tool to read the contents of ISO7816 smart cards. It is extensible with the LUA scripting language.

It supports the following type of cards:

• Bank cards (VISA, MasterCard, CB and UK Post Office Account cards)

• Passports and the Belgian identity card

• Transport cards (Navigo, MOBIB, RavKav and VIVA cards)

• Older GSM SIM cards without USIM data

• Vitale 2 Health card

• Moneo Electronic purse card

• Driver Tachograph cards

• OpenPGP Cards (beta)

It also has limited support for Mifare Classic compatible cards (Thalys card)

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 package provides a communication library for Nitrokey.

This package provides a PC/SC IFD handler implementation for devices compliant with the CCID and ICCD protocols. It supports a wide range of readers and is needed to communicate with such devices through the pcscd resource manager.

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.
